Learn JavaScript use JSON parse and Stringify for JavaScript objects and arrays as JSON data

In this lesson, we'll cover the basics of JSON and how it works. JSON is a standard way of storing data in a readable format, similar to JavaScript objects. We'll start by creating a JSON object that contains an array of people, with each person represented as an object. It's important to note that JSON requires double quotes around property names. We'll output the result to the console so we can see each person in the array.

We'll also demonstrate how to use JSON stringify to convert a JavaScript object or JSON object into a string representation of the object. This can be useful when sending data to an API or saving it to a database. However, the stringified version is not usable as an object and can't be accessed with array methods or dot notation.

To convert a stringified JSON object back into a usable object, we can use JSON parse. This function takes a JSON-formatted string as input and returns a JavaScript object.

In summary, JSON objects are written in the same way as JavaScript objects, with curly brackets and name-value pairs. Arrays are written with square brackets and can contain multiple items. JSON stringify can convert a JavaScript or JSON object into a string, while JSON parse can convert a stringified JSON object back into a usable JavaScript object.
