JSON Parse & Stringify
JSON (JavaScript Object Notation) is the standard format for sending data across the web. It looks like JS objects, but it's just a text string.
Stringify (Object -> String)
Before saving to localStorage or sending to an API, convert JS objects to strings.
Parse (String -> Object)
When you receive JSON text, convert it back into a usable JS object.
Practice
Challenge 1: Create an array of strings, stringify it, then parse it back.
