What is the symbol “!” used for? I’ve seen it many times but I don’t know what it means.

In JavaScript, ! is the Bitwise operator, NOT.
console.log(! true); // -> false
NOT is a negator, meaning true becomes false, and false becomes true.
In many languages, when combined with = it means NOT EQUAL TO.
12 !== 13 // true JavaScript
12 != 13 # True Python
