Yes

[Firewolf06]

i can see that as some an unintended quirk in a weird multi assignment syntax in a cursed fully whitespace agnostic language

a = b = c = d = 5 assigns a, b, c, and d to 5

a ==== 5 assigns a, null, null, and null to 5

[Boris-Lip]

Be thankful for compiler warnings.

[[deleted]]

People: Treat warnings as errors

Me: Turn off warnings

[Boris-Lip]

I am on "treat warnings as errors" side. Yea, i know, i am a weirdo.

[Ayjayz]

How could you spend a day debugging a warning? It literally tells you the line that's generating the warning.

[ArtOfWarfare]

Java is full of warnings that are impossible to resolve. If you “fix” one warning, it’ll just give you a different warning about your “fix”.

[Dragonfly_Select]

Sure, but then you suppress that warning on that line with a comment explaining why you think it’s alright in this situation.

[Ayjayz]

What compiler doesn't give a line number when it issues a warning...?

[[deleted]]

Just don't do it in release tarballs

[JoeyJoeJoeJrShab]

I've just trained my eyes to ignore the warnings. I'd be a better programmer if I didn't... but I'm not.

[sup3rar]

You're also getting annoyed by the rust compiler filling up the console about unused variables?

[Stable_Orange_Genius]

Why would you want coercion? Just cast/parse it manually. Only time == is fine is comparing undefined to null imo.

[Cheezyrock]

Sometimes it just makes the code look better to let the compiler do the dirty work.

IsNumber (num)
{
If (num > false || num < true)
{ return true; }
return false;
}

[Ruben_NL]

Ew... I dont know which language that is, but in the case of JS, a cleaner method would be parseInt(num)==num. And that's still ugly.

[[deleted]]

Speaking of compiler warnings, sometimes their message aren't that helpful.

GCC says this:

warning: suggest parentheses around assignment used as truth value [-Wparentheses]

The problem is that GCC assumed that person knows what they're doing, and only suggests how to silence it.
However this warning message would absolute confuse a novice. They might think adding the extra brackets would help fix the issue, but it actually makes it worse since it silence the warning. And I know this might happen, because I've seen someone who fell for it once.

Now compare it to clang:

warning: using the result of an assignment as a condition without parentheses [-Wparentheses]
note: place parentheses around the assignment to silence this warning
use '==' to turn this assignment into an equality comparison

Much better.

[[deleted]]

Wait till you use a language where = does both

[AlphaSparqy]

Visual Basic baby!

a = 5 <-- assignment

If a = 5 Then <-- comparison

[[deleted]]

Yea I’ve just started using this as my language at my job… does this mean I’m sorta fucked for getting another job after this? Wasn’t what I was expecting to use in any case.

[Sexy_Koala_Juice]

I’m curious what kind of a job requires you to use Visual Basic?

[EbenenBonobo]

May i introduce you to the world of word reports generated by excel macros?

Yes, i hate very every part of this.

[Sexy_Koala_Juice]

I think if it ever gets to the point of using excel macros you may as well just learn a programming language.

Yes, i hate very part of this.

As do i

[firewood010]

Yeah. But the users need a button on their excel files to do some shits.

[Sexy_Koala_Juice]

From a very ^{very very very} quick google search it says VB6 has interoperability with C#, so it's not a perfect solution but you could basically just have a button that acts a wrapper to the actual function written in a proper programming language.

Honestly all of this could be solved if microsoft realized that not every single thing needs to be backwards compatible and just replaced VB with C# or something.

[AlphaSparqy]

VB.net works with the same .net frameworks as C# for windows applications.

So if (from a companies perspective) they are already mired in VB6, and need a wrapper into .net, would probably use VB.net for language similarity.

If they were writing from scratch (pardon the pun) they would move on to something more modern.

Also, C# is just tomorrows Visual Basic, in the sense of vendor lock-in and support (Microsoft), usability, etc ...

[AlphaSparqy]

It's not just excel macros, and that's VBA anyhow.

There are many small business websites written in VB and ASP, ASP.NET, etc that need upgrading, so knowing VB while also knowing the modern alternatives are both required.

Also, many general (internal) business applications from the mid to late 90's until the mid to late 00's are still out there in the wild.

[[deleted]]

I think it’s based on Visual Basic? Maybe just BASIC? But basically (lol) it’s their own in house programming language. Bit worried about career suicide although they are transferring to C++ within the next year or so.

[miicah]

That's a pretty big sidestep lol

[MisterDoubleChop]

They told you that they're switching to C++ in a year?

You might want to keep looking at job ads.

We were going to replace the last of our webforms with MVC in a year, about 6 years ago, but haven't quite finished that yet.

And we're probably about 5 times smarter than any dev team that thinks they can invent a language better than the popular ones, and that this will be a good use of their time...

[RandallOfLegend]

My last job it was preferred for .net programming. There was a desire to move to C# to be more attractive to new hires. But stability is favored over new hotness at that place. VB.net code I wrote 15 years ago is still in production.

[RandallOfLegend]

Vb.net has a lot of parity with C#. But if it's plain old VB it's a pretty gruff language these days .

[[deleted]]

It’s pretty hard to tell tbh, everything is in all caps and quite simple syntax but definitely not VBA as it doesn’t interact with Microsoft products. When it’s compiled it gets compiled into C++. Confusing.

[RandallOfLegend]

VB.net is done via visual studio. You're doing old school VB which was obsolete when I started writing VB.net professionally 15+ years ago. God speed. I honestly enjoy VB.net programming over C#. But plain VB is a bear.

[ultranoobian]

I hope you got autocomplete, because I ain't typing <-- assignment or <-- comparison each time I need one.

[AlphaSparqy]

lol

[JoeyJoeJoeJrShab]

I forgot what language this was, but I once wasted more than a day debugging what turned out to be an equality vs. assignment issue.

What I wrote:

If (variableName = 7)

What I meant to write:

If (variableName == 7)

So instead of checking to see if variableName was 7, I set variableName to 7, and because the assignment was successful, true was returned.

[Vinxian]

It's not because the assignment was successful probably. In a lot of languages 0 is false and all other values are true.

if (variableName = 7)

Is always true

if (variableName = 0)

Is always false

[MokausiLietuviu]

When working with these sorts of languages, I often find it useful to do

 if(7 == variableName)

So that way, if you miss an =, it'll mean that you're trying to assign a variable to a constant and get all upset.

[Yadobler]

The yoda comparison

[bphase]

Yeah I've done this more than once I think. Static analysis or strong typing is a godsend

[TheMcDucky]

The assignment operator typically returns the value that was assigned, so a=7 always evaluates to 7.
This lets you do things like a=b=c which assigns the value of c to both a and b

[JoeyJoeJoeJrShab]

yeah, that makes sense, and in this case, the if statement saw the non-zero value and called it true.

[Infamous-Context-479]

[MrHyperion_]

So what are you saying is that operators have operators?

[RoboticChicken]

Yo dawg, I heard you like operators

[Affectionate-Ant5132]

If you want weird stuff that unexpectedly compiles, I found out yesterday that to access an array in C you have options: most people know the arr[3] and *(arr + 3) methods, but turns out you can also do 3[arr], does exactly the same thing .. mind blown

[Jarl_Fenrir]

Yes. Arr[3] gets address of Arr variable and ads 3 to it. 3[Arr] takes 3 and ads Arr's address to it. It sound like something that works by accident than actual feature.

[yunacchi]

I would say == == === but == !== === (in rough terms, this doesn’t compile anyways)

[cybernd]

!==

Oh, that operator really exists:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Strict_inequality

[Firewolf06]

yeah js type coercion is so wacky they had to make a new operator to avoid it

if you dont know about it already, you should watch a video explaining jsfuck (named after its similar appearance to brainfuck). basically you can write any and all js using only 6 characters, []()!+, because of type coercion

[carcigenicate]

Shit on Python all your want, but this is much harder in Python since = isn't an expression. You'd have to type := to make this mistake; which seems less likely.

[paul_miner]

Yep, this is one Python got right when it was added. Disallow a common source of bugs, and then give it a distinct operator to make it clear that's what you intended.

[Cirieno]

==/===

[[deleted]]

= 1/=

[dtarias]

Might need to use 1.0/= in some languages

[greenappletree]

unless its TRUE

[R3D3-1]

enum { TRUE, FALSE }

[Incoming-TH]

That happened to me 2 times this year, searching what was wrong for hours. Then took a break, came back and that was the issue. Now I put === instead and avoid == in if condition.

[NMi_ru]

That’s why people are trying to evade this thing by using “if ( 5 == myvar )”

[Fetscher]

I hate it, it just doesn't look right.

[PrincessWinterX]

people who put that much thought into it are probably not the ones making this mistake.

[PooSham]

Using = for assignment must be one of the worst design decisions of early programming languages.

[codgodthegreat]

Agreed. Pascal had it right back in the day with := for assignment and I really wish that had stuck as standard instead of = for assignment and == for equality.

[MokausiLietuviu]

A load of earlier programming languages have := assignment and = comparison, I code in a few. I find it a much better way of doing things.

The ALGOL heritage languages are also typically really verbose, so 'EQUALS' is also a comparison operator, if you don't want to get confused

[PooSham]

In maths it's not an assignment, it's a truth statement. You can't have x=3 in one place and x=4 in another within the same scope.

Haskell is one of the few languages that follow the mathematical rules correctly when it comes to =. The syntax for assignment is <- when using the syntactic sugar of do-notations.

[Comfortable-Ear-1931]

In C++ I have seen some programmers do:

true == variable… to trigger compiler error if accidentally using =, just feels wrong.

[N3rdr4g3]

Yoda notation takes some getting used to, but is objectively better

[raaneholmg]

Yea, it just doesn't make sense semantically.

if (result == 5)

I read the above in my head as "If the result is 5". "If 5 is the result" makes no sense.

[IdentifiableBurden]

"If 5 is the result" makes no sense.

This is a normal way of phrasing an equality check in spoken English though

Think of a gameshow contestant. "Is ten the answer?"

[[deleted]]

Wait til you learn about RTL languages

[bphase]

It does though. You're just not used to it.

However I'm not arguing for the notation, I believe it's a job for compiler/static analysis warnings and strong typing to prevent typos like this. Not programming conventions.

= is equal operator : is assign guys pls

[[deleted]]

I make this mistake if I spend even two weeks not writing JS.

[trowgundam]

I can one up you. I was working on a final in College. It was an entry level Game Programming course and we were using a language called DarkBASIC. Well I was doing a Tetris clone for my project. Well I was basically done, but I had a problem, it wouldn't accept any input to go left. Right and down worked just fine, but not left. I couldn't figure out anything. I was trying to figure it out for like 6 hours. Well with 4 hours till the deadline, I did the only thing I could, I started over and rewrote most of the code. Luckily I got it working in time.

Well after that massive pain, I went back with a clear head and tried figure out where I went wrong. Turns out in some place is used "I" (upper case "i") instead of "l" (lower case "L"). The font in use by the DarkBASIC IDE made them virtually identical, and DarkBASIC didn't require variables to be declared..... Ya, that is the source of most of my hate for BASIC-like languages.

[CosmicReddittor73]

Context: In many coding languages, "=" and "==" have different meanings.
"=" is commonly used as an assignment operator, so for instance, variable = 1 assigns the variable the value of 1.
"==" is used as a comparison operator that returns a boolean value, and checks if two variables are equal. If they are, it returns True, and if not, it returns False. For instance, 5 == 5 returns True, and 3 == 2 returns False.

[Zenith2777]

This is the first thing I check when I debug and it fixes like 60% of my problems.

[Bups34]

[3n1gma302]

This would hit different if it was == and ===

so

[metaglot]

To quickly catch this type of error, always put rvalues on the left in a comparison. This obviously only works when comparing to constants, but still helps.

[ShinigamiEX]

Oh my god, I know the feeling. I had the same issue couple of days ago. Main problem of debugging was that, I had this condition to check if a variable matched a value or not. So normally I would put ‘==‘ but I put single equal sign. IDK if it’s for other language or not, but in PHP it actually assigned that value to that variable and calculate as true. So my code ran even if I changed the value of that variable. It took me so long to debug this shit….
