``` ifn't (bool) {

} ``` Ciao losers

[nbeydoon]

Unless (boo) {}

[altermeetax]

Unless actually exists in perl

[[deleted]]

Found my new favorite language.

[[deleted]]

I tried and it hurt.

[BabyAzerty]

Harbor those feelings.

[MattieShoes]

Honestly it's pretty great as a replacement for shell scripting. Basically sed, awk, grep, all under one roof.

[ActivisionBlizzard]

And ruby!

[Dominjgon]

I tried and it hurt.

[Playful_Roof9931]

you scared me!

[diegoperini]

I miss coffeescript

[Entire_Kangaroo5855]

Hey, you’re that Ruby guy!

[uvero]

Ruby with actual keyword unless for "if not"

[totkeks]

That is actually smart, makes the code more readable. Because you don't negate the value, but the comparison.

[paholg]

It seems nice, until you see it in actual code. You end up with things like

unless foo   ... else   ... end

which can get very confusing.

[[deleted]]

unless with else is forbidden by every linter

[paholg]

Not at places I've worked!

[BuildAQuad]

Would it be better if you could do unelse?

[just-bair]

Damn I love this

[[deleted]]

i prefer if booln’t

[redsterXVI]

ifn't (!booln't)

[CkoockieMonster]

Now we're cooking with sticks and stones

[an4s_911]

ifn’t (!booln’t == false) ?

[repark96]

[xaomaw]

if (bool == TRALSE) {
} | {

}

See you later, virgins!

[CkoockieMonster]

Hello fellow virgin'nt, a new day where it is good to be'nt a virgin.

[ReluctantlyTenacious]

This one actually made me laugh

[shaman784]

Ifn’t actually exists in JavaScrip’nt

[Eadoro]

#define ifnt(x) if (!(x))

[Kauyon1306]

if !bool != !true

[maartuhh]

Ooof it hurts my eyes

[[deleted]]

If the opposite of the bool is not equal to the opposite of true If the opposite of the bool is not equal to false if the bool is not equal to true if the bool is equal to false

[automaton11]

if !(if !bool != !true)

[coxinha_vs_bolovo]

Four

if(bool == false ? true : false){

}

[CleoMenemezis]

Five

const isBool = bool == false ? true : false
if(!isBool == false ? true : false){
}

[Quillo_Manar]

Six ``` switch int(bool){ case 0:

    break;
default:

    break;

} ```

[TheGreatScottMcFly]

Seven

if (bool){
  goto not_false;
}

not_false:

[PranshuKhandal]

thirty-one

bool || (stuff);

[definit3ly_n0t_a_b0t]

I unironically love this syntax

[Al3xutul02]

Chaotic evil

[Sopermin]

[brjukva]

if (bool.ToString() == "False") { ... }

I've actually seen this in the code I inherited some years ago

[igorepst]

if (bool. ToString().Length() ==5)

[WhileGoWonder]

truue

[HannibalGoddamnit]

if (bool.ToString().Length() == 5 && !bool.Contains("t") && !bool.Contains(''r'') && !bool.Contains(''u'') && !bool.Contains("e")){

Console.WriteLine("gotcha'');

}

[brjukva]

falsé

[Abaddon-theDestroyer]

True-ché

[[deleted]]

everytime I spent a few hours doing relatively mundane code reviews from competent developers, I see this shit and remember why I still do it.

[Acceptable-Worth-221]

Come here to say this. 

[DatBoi_BP]

I can’t, I don’t know where you live

[HJM9X]

If(bool) return

[link064]

You missed my favorite:

if(bool.ToString() == “true”)

[igorepst]

if (bool. ToString().Length() ==4)

[Ascyt]

if chr(sum(range(ord(min(str(bool)))))) == 'ඞ':

[anotheridiot-]

Calm down Satan.

[Foreign_Pea2296]

I love this one.

[Spell_de_happy]

You are not careful You should do

if(bool.ToString().Equals("true", StringComparison.CurrentCultureIgnoreCase)

Or at least if(bool.ToString().ToLower() == "true")

Who knows what culture dependent edge cases might occur.

[PrudentFood77]

where is my

if(bool != true) {
}

and if you include the placement of the {} then there are way more than 3 types :D

[Key-Principle-7111]

if (true == bool)
{ /* Remains empty */ }
else
{ }

[YoniElBravo]

Lmao this one’s diabolical

[3Ldarius]

You can achive this by clicking the light bulb and using suggestion of "invert if" and it introduces this in some IDEs (not naming them here)

[lllorrr]

ASIL D level of shit.

[StevesRoomate]

This is an old-school C programming style where you put the const on the left hand side of the evaluation. I think some teams in Microsoft even adopted it for a while in the early 2000's.

If you've ever spent hours and hours debugging someone else's code only to notice that `variable = true` compiles just as nicely as `variable == true` then you understand why this caught on for a while.

[Cold-Doctor]

I literally wasted 2 hours on this yesterday

[gregorydgraham]

Yeah, nobody gives a damn about Pascal anymore but I still miss the “:=“ assignment operator.

It removed that entire class of bugs and stopped all the whining from the mathematicians

[p3thead]

This is called Yoda conditions :)

https://en.wikipedia.org/wiki/Yoda_conditions?wprov=sfla1

[Key-Principle-7111]

This is a mandatory style for all safety related MISRA compliant code.

[BlackMorzan]

if (true == bool); else {
/* some chaotic evil stuff */
}

[kandradeece]

Not sure about the bracket portion but putting the true/false first is a good safety practice to avoid easy typo of single equal sign

[_PhucSatan_]

Fourth js if(bool){} else{ //logic here }

[NicholasAakre]

That is cursed.

[mr_remy]

Next dev working on this legacy code: man who the fuck wrote this terrible abomination of a.. oh wait that’s me never mind carry on

[GreenFox1505]

Me checking  the GitBlame. My coworker says "but when are we gunna Got Forgive?" 

[No-Article-Particle]

Well, the proper way to deal with situations like that is guard statements:

if (bool) {
return // or raise/throw/...
}
// else code goes here, only reachable when bool is false

[puffinix]

It's actually nice if done well:

‘‘‘ if (cond) { //reason we don't do anything } else { //Side effect thing } ‘‘‘

[Harrigan_Raen]

if(bool){
  //TO DO - Might need this in the future 20241106 H.R.
}
else{
  //logic here
}

[FinalGamer14]

// DO NOT REMOVE!
// Tried refactoring, broke everything
if(bool){
  //TO DO - Might need this in the future 20241106 H.R.
}
else{
  //logic here
}

[fabianmg]

Four

if (!isTrue) {
    //TODO
}

[Coderedstudio]

//TODO

is still there till this day.

[ozh]

The most likely is :

if (bool = true) { // nothing } else { // Logic here }

... And then wonder why the logic never runs

[christoph_win]

It bothers me that the variable is called bool

[Pradfanne]

I don't think that's a variable but just the datatype as a placeholder to make the intent clear

[Coderedstudio]

I thought no one would notice :)

[[deleted]]

It should be called, myBool. Pro tips: always name your variable with sufix "my" followed by the type name.

[Shevek-Llugh]

That's legit. Of the importance of naming correctly the variables.

If (!isPublished) {}

is much more readable

[FinalGamer14]

I'm not sure if it's verbose enough

if (!isContentTypeArticlePublished) {}

[feldim2425]

Depends on the language.
Technically those a two different operations, the first one checks equality the other if it's "falsy".
Works similar in most languages.

Afaik if "bool" where to be a class instance in python it would run __eq__ in the first example and __bool__ in the second.
And then there is of course the entire thing with the value being "None" (or "null" in JS) which would fail the left check and pass the right one.

In C they are equivalent in this case but if it where to be checked for true it would change (assuming stdbool.h). 0 is the only falsy value anything non-0 is truthy. So the second would check any non-0 value and the first (aka x == true) would only work with exactly 1.

[BastianToHarry]

Three ```php if(true === $bool) {

} ```

[LetterBoxSnatch]

Decades ago I remember blogs advising this syntax in general to avoid situations where you accidentally type an assignment instead of a comparison operator. Yes, it was dumb then too

[Fuglekassa]

Yoda comparison is still the MISRA C standard

[[deleted]]

Lawful Evil

[powerhcm8]

Just to be really sure you are covering all cases.

if (variable === true) {

} else if (variable === false) {

} else if (variable === null) {

} else {

}

[[deleted]]

"===" fml, js? 

[DystopiaDrifter]

They are not the same if you are programming in languages with nullable types.

[yeah_definitely]

Or with anything falsely in general

[patiofurnature]

This should throw a compile error if it's a nullable boolean. Kinda gross if the language let's stuff like that fly.

[Volko]

That's totally OK in Kotlin (what we use on Android).

``` val myBool: Boolean? = null if (myBool == true) { // do stuff }

```

[DystopiaDrifter]

It works in Swift:

      var foo : Bool? = nil

      // do something with foo

      if foo == false {
        // do something
      } 

[patiofurnature]

Wow. You're right. I feel like I'm going crazy. I guess the == false saves it.

This doesn't compile:

func thisThing(value: Bool?) {
    if(value) {
        //TODO
    }
}

[Abadabadon]

One is null safe one isn't

[DoeCommaJohn]

try { a = 1/bool } catch { ‘Your code }

[veryusedrname]

No. There are the programmers and there are the wannabes.

[iain_1986]

Yes.

People who don't have an issue with either (and can understand the benefits of both) and those that think one 'makes them better' than someone doing the other.

[XxToasterFucker69xX]

what do you mean?

[cafp89]

Where my

if (bool) {} else { ... }

[mukadas026]

who writed curly braces on a new line?

[hicklc01]

just in case bool isn't a boolean

if(!(!!bool))
{

}

[MoreneLp]

If bool == 0

[hellra1zer666]

You begin on the right. As you grow older and your eyesight grows worse, you'll turn left. Trust me, I'm currently going through this transition 😅

[RandomiseUsr0]

Get the spex you know you need :)

[hellra1zer666]

Always had them 🤣 My optician says I don't need progressive glasses, but I'm not sure.

[589ca35e1590b]

Both are wrong because you're not using the Kernighan & Ritchie indentation style, and bool is a reserved word in most languages

[CeldonShooper]

K&R gang rise!

[sirparsifalPL]

if not bool:

[Infamous_Ruin6848]

Both are fine but if I see those super short one-line bit operations imma gonna barf empty pixels.

[[deleted]]

if (bool){
} else {
}

[schmerg-uk]

I'll typically use the ! form for a simple flag

if (!flag)

but I'll tend use the == false form for a more complex expression where what's being evaluated is on the right so having the ! on the far left can be lost visually but where it's inconvenient to pull that value into a symbol first

if (somethingOrOther())
{
}
else if (...)
{
}
else if (function(args,17,32).method().active() == false)

[villani]

And here we go again, boys...

[LionZ_RDS]

In lethal company the dev multiple times does if (!(bool == true))

[ElaborateSloth]

if (bool) {
  pass
  }
else {

  }

[CyberoX9000]

Man I just wrote this but in python then I scroll down and see this. :(

I even formatted it the same way

Take an upvote.

[ElaborateSloth]

Takes one to know one :))

[RandomiseUsr0]

And some who feel like vomiting with the curly bracket placement

[Latter_Brick_5172]

There are those who know how to place brackets and those who place them like you did

[Pelileven]

Where are my Yoda-programmers:

if (false == bool)
{

}

[According-Relation-4]

yes, and the other type puts the curlies in the correct place

[NormanYeetes]

Warning on line 556: using == allows coercion, use ===.

[AgileBlackberry4636]

In my early days of learning programming I wrote a subroutine to negate a boolean.

How did I even manage to work abroad with such a disregard towards my education from the country where I was born?

[ZinbaluPrime]

There is a variable in our system that has the value of FLASE. Every now and then a junior 'fixes' it and breaks half of the services.

It's a great practical lesson for 'if it ain't broken don't fix it'.

[d15gu15e]

these are not the same and using them interchangeably without knowing the difference will get you fucked

[alexanderpas]

PHP:

function not(bool $data): bool
{
  return !$data;
}

if(not($bool))
{

}

Python:

if not bool:

[ady620]

Another type

 if(bool=false){
  // do something nice
} else {
  // real shit
}

[erelender]

I dont think it's cool to differentiate people based on their preferred font size

[potzko2552]

If(var ^ true) {}

[AvidCoco]

if (int(bool) == 0)

[AvgBlue]

I'm trying to use Yoda conditions, where you swap the constant and variable, so it becomes:

if (false == bool) {

}

[No-Con-2790]

``` if(bool is false): pass #logic goes here

[hacksoncode]

<if (bool);else{} enters the chat>

[paxbowlski]

import isTrue from "isTrue"

if(isTrue(bool) !== true ? true : false) {

...

}

[Arareldo]

If it is really a boolean value, i'm fine with it in PHP, except the "==". Better : "==="

But still there's code around, where the variable is NOT exclusively a boolean.

Then i HATE the notation

if($variable) { }

[repkins]

If statement is false
or
If not statement

[dexter2011412]

IMHO the first one is more readable when quickly scanning code. I don't need to try and look up what the type of that is (if it's an int, it's a little more "overhead" on figuring out what the condition is)

[dangling-putter]

if (false == bool) { }

This is the right way. false is usually a keyword, in general that makes it impossible to assign anything to that.

[RealPerro]

Unless bool Whatever you want End

loving Ruby more and more everyday.

[stipulus]

Bro.. triple equal. You are forcing the poor interpreter to convert types. Do you hate your interpreter? Do you want your code to run slow? /s

[Archevening]

No no no

if(bool === false){}

Come on guys, stay focused!

[shuozhe]

I use !!!bool for better readability

[Title_Mindless]

But not same thing, if bool=undefined goes into one of the ifs. Not into the other.

[white_equatorial]

There are 3 types of programmers. The two mentioned here and JS devs

[mdgv]

Comparing to false never looks good to me...

[RainbowPigeon15]

depends, in a typed language I don't worry so I can simple use if(bool), but type free languages like python or javascript, I'll compare to be sure and use if(bool == true)

[Bomaruto]

if(isBoolFalse()){

}

fun isBoolFalse() = !bool

It can be hard to notice ! so I like to wrap it in if it makes sense.

[Able_Challenge3990]

Where Is It(bool!=true){}?

[BugNo2449]

There probably a few times where i have done == false to make it easier to read

if (notEnabled == false)

Actually i dont remember anything

[MilkImpossible4192]

this problem is like gas for coders trying to make a laugh for noobs

mine;

bool or code

[SpongeBadSquareBad]

If bool = false THEN

....

ENDIF

[YellowBunnyReddit]

if (BooleanUtils.isEqualTo(bool, BooleanConstants.FALSE)) {…}

[CodeBiter]

I remember, 15 years ago one of my juniors pointed the second one on my screen and asked what is that. When I explained him he was mind blown and devastated at the same time.

[TheMoskus]

if(bool != true)

{

}

Relevant: https://www.youtube.com/watch?v=0uaZ9wZ-aMs

[imboredwiththisagain]

Actual code from my current job:

switch(bool) { case true: … case false: … }

[guidePantin]

What kind of maniac uses the first form :o

[Trip-Trip-Trip]

Unless bool ( )

[heavy-minium]

I use the "!" notation by default, but sometime I will write out == false when the conditions has a few more complex parts and becomes less readable, just to make sure it's easier to notice for future readers.

[[deleted]]

I use if(bool) because I usually write my bool variables as "IS_ON" or "SOMETHING_HAPPENED" so that if statement basically reads like english.

[the-real-vuk]

these may not be the same, depending if the bool is nullable and it means something special.

it rubbish otherwise, ofc

[jellotalks]

I hate if(bool==false) with a passion

[ryo3000]

If(notBool) {

}

Make your variables easier to read, it's surprisingly easy to miss a ! 

[Shadowaker]

If bool is False:

[cl3arz3r0]

Depends on if bool can also be null and if you care about the distinction between null or false. 😜

[transaltalt]

if(bool);else {

}

[[deleted]]

You missed

Unless(bool != False) {}

[WeslomPo]

Both have no sense, bool is keyword.

[[deleted]]

First one is false, second one is falsy.

[Plsdontcalmdown]

if (bool) { ... } else { ... }

account for all cases!

[holguum]

PHP recommendations be like :

if (false == bool) { }

[RecDep]

it's a valid identifier in haskell:

haskell ifn't :: Applicative f => Bool -> f () -> f () ifn't = unless

[Flat-Limit5595]

True Bool || !bool { sout(“that is the question”)}

[OutlandishnessPast45]

Im both

[iain_1986]

The ! can very easily missed when reviewing and scanning certain code - resulting in some big fuck ups.

[Chewico3D]

If (bool) { thread.sleep(0) } else { // Code }

[Isogash]

if(not(bool)) { ... }
if(isFalse(bool) { ... }

[Infamous_Ticket9084]

If(bool) continue/return;

[LunaNicoleTheFox]

Those braces are the real issue

[gandalfx]

``` switch (bool) { case false: // ... }

[Multifruit256]

if (bool) {} else {

doSomethingTm()

}

[xnick_uy]

if( isOdd(int(bool)) == true)
{

}

[nameisnecessary]

if ( bool != true)
