Some things I like about ES6

1. Arrow functions are really handy:

  ["the", "red", "fox"].map(word => console.log(word))

is much cleaner than

  ["the", "red", "fox"].map(function(word) {
      console.log(word)
  })

2. Imports, while more ambiguous than `require`, look quite nice:

  import React, { Component } from 'react';
  import Block from './Block';

vs

  var React = require('react');
  var Block = require('./Block');

3. Exports are cleaner and streamlined

  export default myFunction()

vs

  module.exports = myFunction()

So while ES6 is more ambiguous than ES5 and has a higher learning curve, I think it's much cleaner and looks more like a proper programming language. ES5 feels like a homegrown hacky language in comparison.
