# OH FUCK YOU TOO JAVASCRIPT

Null is neither true or false or a number so no, you can’t compare it.

Null is a black hole that can’t be measured but we know it’s there, well not there actually.

Lol ikr, it's almost like JavaScript runs on sorcery.

5 seconds of google would get you:

"

In Summary:

Relational Comparison: if both values are not type String, ToNumber is called on both. This is the same as adding a + in front, which for null coerces to 0.

Equality Comparison: only calls ToNumber on Strings, Numbers, and Booleans.

I'd type a long reply, but since this gets posted I'll i stead say:

TL;DR: ===
• 0
NaN === NaN = false is way worse...
• 1
Null is zero and negative
• 1
Null is Schrodinger's constant lul

Why are you comparing values with something that, by definition, is the lack of a value?

You're the purple plastic pancake, not JS.

@olback its false in any language its the IEEE 754 specification that any NaN comparison is false.
• 1
Does null >= 0 return true as well
• 0
@olback parse your strings as numbers then
• 0
Hurray! A fellow Terminator user!

Nope don't blame it on JavaScript. I know it's not the best language but it's something you should know about the language

Seriously guys, null <= 0 evaluating to true is pretty fucked up.

Since nobody explains the stuff with larger than and smaller than:
< and > check if the value is in the requested range
I.e. Null > 0 is false because null is not in the range of greater than zero

>= and <= check if the value is missing in the opposite range
I.e. Null <= 0 is true because null is not in the range of greater than zero

@Astatos

On one end I feel like that makes a lot of sense, but on another end I feel like that makes absolutely no fuckin' sense.

@C0D4 in js null is false (Boolean(null)==false)
• 1
@Grexius @Astatos is explaining what the operators do.

When performing <= & and >= if both types are not strings, they have toNumber called on them.

Thus 0 <= 0 = true

This is all in the ECMA Script spec. Does no one read ;_;
