But then why 2 == true if true is converted to 1

    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..

    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.
