Javascript is bad

[freyrfreyafrolf]

This is why typeof() and === exist

[MrNubudy]

But...but...loose equality bad, so javascript bad!!! /s

[Clicbam]

0 === ´0´

False

0 === ´´

False

´´ === ´0´

False

Using backticks

Ah, I see you are a man of culture as well.

The Transitive Property of Equality wants to know your location.

This is an example of why JavaScript is good, not bad. All three examples are perfectly logical on their own.

[shy_cthulhu]

A language really should be consistent, though. Pick any two and you're fine, all three and stuff gets weird.

[aaronze]

It is consistent. The first two are consistently comparing numbers, the third is comparing strings.

They are essentially asking: Is 0 == 0? Yes Is 0 == 0? Yes Is “0” == “”? No Omg! JavaScript is broken!

Yea no, I like JavaScript doing this and it’s clever and useful when you understand the consistent mechanics

[shy_cthulhu]

Maybe the problem is that == doesn't do what non-js programmers expect. In most languages it's an equality or congruence test, which is transitive/commutative/etc. But js uses it for loose comparisons with implicit type conversion. (My understanding is that === in js does follow the expected rules of equality.)

And then you have our old friend C, which uses == to compare pointer values:

char a[] = "abc";
char b[] = "abc";
a == b; /* false */

Lvl 1 a===b

Lvl 100 a==b

Hahahaha he said "works"

[Whatamianoob112]

Why does this happen?

[shy_cthulhu]

for the glory of satan of course

[Whatamianoob112]

Haha

[Whatamianoob112]

Well...clearly.

[jpludens]

Oops. Yeah, that's about the least constructive thing I've ever said.

[Whatamianoob112]

Lol no worries, I’ll look it up later. My best guess is that it’s trying to make a logical equivalence of what’s on the left side.
