innerScope.js

function head() {
  console.log("HEAD");
  /* Some more logic that goes down here then will return function */

  return function body(arg) {
    console.log(arg);
    function inner() {
      console.log("INNER METHOD");
    }
    // return "SOMETHING USEFUL";
    return { inner };
  };
}

let p = head();

p("HELLO BODY"); //will print "HELLO BODY"
p("HELLO BODY 2").inner(); //will print "HELLO BODY 2"
