Javascript Array Iterative Methods (Part 4): forEach

[ * ] About the video

Actually, JSON isn't always an array, it can be just a big ol' object with many properties and sub-documents. The forEach can be used in many ways but most of the times you're going to use it to iterate over an array of objects as in the last part of the video (the API part).

The ES6 implementation, although simple and clear, needs you to transpile ES6 syntax with Babel or Traceur. Babel is the way to go nowadays as it's in build tools and as a browser library. Even NodeJs 4, 5 and 6 implements most of it.
