Example of why ES6 is cool

convert_to_es6.js

// Converting an ES5 function ES6

// Start
function getWords(text) {
  return text.split(/\s/)
}

// Use const declaration
const getWords = function(text) {
  return text.split(/\s/)
}

// Convert to fat arrow
const getWords = (text) => {
  return text.split(/\s/)
}

// Use round brackets
const getWords = (text) => (
  return text.split(/\s/)
)

// return is now implicit
const getWords = (text) => (
  text.split(/\s/)
)

// But we don't need brackets for a one liner
const getWords = (text) => text.split(/\s/)

// ... or parens in the args list
const getWords = text => text.split(/\s/)
