learn JSON from head to toe

what is JSON ?

• JSON - JavaScript Object Notation

• JSON is a lightweight format for storing and transporting data.

• JSON is often used when data is sent from a server to web page

• JSON is language independent

The JSON format is almost identical to JavaScript objects.

• In json keys MUST be in strings, written with double quotes

• In JavaScript object, keys can be strings, numbers, or identifier names

In JSON, values must be one of the following data types:

• string
• number
• object (JSON object)
• array
• boolean
• null

In javaScript object , valuse must be one of the following data types:

• string
• number
• object (JSON object)
• array
• boolean
• null
• function
• date
• undefined

🚥JSON.stringify( )

When sending data to a web server, the data has to be a string.

So thats why while before sending data we need to Convert it from a JavaScript object to a JSON

To make this happen we need JSON.stringify( ).

🚥JSON.parse( )

Likewise while we receiving data from a web server, the data is always a string.

So we need to Parse the data into javascript object to use the data in out applications.

And for this action we need to use JSON.parse()
