It's not. Just tried in my Browser Console:

2 == true // returns false

I genuinely wasn't aware of that. I must be getting javascript confused for almost any other language. I wonder how many times ive !!'d a value to make that work without actually absorbing that into my head now..

2 is not == true, but !!2 is true

[–] Telemachus93@slrpnk.net 3 points 2 days ago (1 children)

In other languages that shouldn't be equal either though, right?

Maybe you meant

if (2){
console.log("nonzero ints are truthy")
}
else {
console.log("no they're not")
}

Which would output

nonzero ints are truthy

and that would actually work in all languages I know. But that's different from being equal.

Yeah its checking for not null with if isnt it. Maybe thats what has me confused
