Pretty-print JSON in Ruby

When receiving a JSON payload it can, of course, be useful to see it in a more readable way. Turns out there is a built in utility in Ruby that can help with this.

Kernal#j & Kernal#jj

Utilizing the Kernal#j method:

foo = {name: "Matt", company: "Hashrocket"}

=> j foo
{"name": "Matt", "company": "Hashrocket"}

Utilizing the Kernal#jj method:

foo = {name: "Matt", company: "Hashrocket"}

=> jj foo
  "name": "Matt",
  "company": "Hashrocket"
