2-> A closure gives you access to an outer functions scope
3   from an inner function
4
5const outerFun = (a) => {
6  let b = 10;
7  // inner func can use variable/parameter of outer funcion
8  const innerFun = () => {
9    let sum = a + b; 
10    console.log(sum);
11  }
12  return innerFun;
13}

2//example
3function init() {
4  var name = 'Mozilla'; // name is a local variable created by init
5  function displayName() { // displayName() is the inner function, a closure
6    alert(name); // use variable declared in the parent function
7  }
8  displayName();
