ES6: replacing an IIFE (immediadly invoked function expression) with a block

scoping.js

// This is used when you want to make your program private (nothing leaks into the global scope of the window)

// BEFORE - using an IFY
(function(){
  var name = 'mara';
  console.log(name);
})();

// BETTER - using a block
{
    const name = 'mara';
    console.log(name);
  }
