Calling a Function defined inside another function in Javascript

Question

I am calling a function on button click like this:

​

function outer() { 
    alert(\"hi\"

You can also try this.Here you are returning the function "inside" and invoking with the second set of parenthesis.

function outer() {
  return (function inside(){
    console.log("Inside inside function");
  });
}
outer()();

Or

function outer2() {
    let inside = function inside(){
      console.log("Inside inside");
    };
    return inside;
  }
outer2()();
