How to Setup Babel es2015 Javascript on Windows 8.1?

First create a folder:
Then CD into that folder through CMD
Then do the follow in command-line

npm init
npm install -g babel-cli
npm install babel-preset-es2015–save-dev

Then create app.js.es6 file

Then use this example code:

class Person {
 constructor(name) {
  this.name = name;
 }
 greet(){
  return "Hello I am ${this.name}";
 }
}

let person = new Person("Tyler");
console.log(person.greet());

babel app.js.es6 –presets2015 | clip

Clip copies the string from commandline. Then you should get the follow code output:

"use strict";

var _createClass = (function () { function defineProperties(target, props) { for (var i = 0; i < props.length; i++) { var descriptor = props[i]; descriptor.enumerable = descriptor.enumerable || false; descriptor.configurable = true; if ("value" in descriptor) descriptor.writable = true; Object.defineProperty(target, descriptor.key, descriptor); } } return function (Constructor, protoProps, staticProps) { if (protoProps) defineProperties(Constructor.prototype, protoProps); if (staticProps) defineProperties(Constructor, staticProps); return Constructor; }; })();

function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }

var Person = (function () {
 function Person(name) {
  _classCallCheck(this, Person);

  this.name = name;
 }

 _createClass(Person, [{
  key: "greet",
  value: function greet() {
   return "Hello I am ${this.name}";
  }
 }]);

 return Person;
})();

var person = new Person("Tyler");
console.log(person.greet());

Now we want to create an index.html file

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title></title>
</head>
<body>
 <h2>ES2015</h2>

 <script src="app.js"></script>
</body>
</html>
