Understanding

ES6

React

ReactNative & Redux

Contents

ES6

Arrow functions

Nicer syntax for anonymous functions

// ES5
function (x, y) {
  return x + y
}
// ES6
(x, y) => x + y
// Example
var bozoItems = items.filter(item => item.is_bozo)
// Can also use multiline.
var sum = (x, y) => {
  console.log('The sum is...')
  return x + y
}
