Lebab

lebab transpiles your ES5 code to ES6. It does exactly the opposite of what other transpilers do (like babel and traceur)! If you want to understand what lebab exactly does, try the live demo.

Why?

Still coding this way? Think twice!

var SomeClass = function () {
  console.log('This is the constructor.');
};

SomeClass.prototype.someOuterMethod = someFunction;

SomeClass.prototype.someInnerMethod = function (birthYear) {
  var result = 'Your Age is : ' + (2015 - birthYear) + ' and you were born in ' + birthYear;
  return result;
};

Object.defineProperty(SomeClass.prototype, 'someAccessor', {
  get: function () {
    return this._some;
  },
  set: function (value) {
    this._some = value;
  }
});

function someFunction(a, b) {
  return a + b;
}

Usage

Install it using npm :

$ npm install -g lebab

Transpile your old-fashioned code using the lebab cli tool.

lebab es5.js -o es6.js

And the result for the code above is :

class SomeClass {
  constructor() {
    console.log('This is the constructor.');
  }

  someOuterMethod() {
    return someFunction.apply(this, arguments);
  }

  someInnerMethod(birthYear) {
    var result = `Your Age is : ${ 2015 - birthYear } and you were born in ${ birthYear }`;
    return result;
  }

  get someAccessor() {
    return this._some;
  }

  set someAccessor(value) {
    this._some = value;
  }
}

function someFunction(a, b) {
  return a + b;
}
