Challenge: Find the value of a JSON key
(chiming music) - [Instructor] This is your first challenge in the string of the chapter and it is to write the method that traverses a JSON document and retrieves a value of a given key. You should be able to call a method retrieveValue and parser the key name and a JSON string to parse. To make it simple, let's just make it return a value. If the key's value is a string or a number, we don't need to write logic that returns an array or an object. And don't forget, write the appropriate unit tests. The estimated completion time for this task is about 20 minutes.
