# While in IRB, use the Ruby JSON library with:
require 'json'

# Then pass stringifed JSON content into it, surrounded by single quotes:
JSON.parse('stringified json here')

# In this lecture we learned a new Hash method:
hash.delete(:key_or_string)

# This will remove by the key AND the key's corresponding value from a hash.
# Example:

person = { name: "Ryan" }
person.delete(:name)
person # => {}
