Tell us what’s happening:
why there is "(" first function and at the end") ();"
Your code so far
const increment = (function() {
"use strict";
return function increment(number, value=1) {
return number + value;
};
})();
console.log(increment(5, 2)); // returns 7
console.log(increment(5)); // returns 6
