Video for understanding JSON, objects and arrays: Basic JavaScript

I thought this part was tough and I couldn’t find any simple documentation on it. So I found this great video. by Traversity, he makes a lot of videos that you can code a long to as well.
This video helped but after 18 min he goes into Ajax and node very briefly to show how your JSON is uploaded to a server…which I found useful because it gave me context to the knowledge learned.
