Parentheses in JavaScript

Question

can anyone explain why the closing parentheses are at the end, not inside the curly brackets.

let num = [1,2,3,4];

num.forEach(function (e) {
console.log(e);
});

Answer 1

the functions wrapped with parenthesis are called “Immediately Invoked Function Expressions" or "Self Executing Functions.

Answer 2

It is inside and also outside.
It started outside curly brace so should close outside curly brace.
it just added a function in ( here ); which aplied to every num element...
