- Can be used with modern programming languages
Alright, now let's jump straight to JSON!!
JSON - Syntax
- Data is represented in key/value pairs, similar to dictionaries in Python!
- Curly braces hold objects and each key is followed by a colon (:).
- Key/Values pairs are separated using commas.
JSON - Data Types:

let objName = {string: number_value, ...}
Example:
let obj = {marks: 97}
Strings:
Syntax:
let objName = {string: "string_value", ...}
Example:
let obj = {name: "Anurag"}
Booleans:
Syntax:
let objName = {string: true/false, ...}
Example:
let obj = {loves_creating: true}
Arrays:
Syntax:
let objName = {string: [ values ], ...}

}

Syntax:
let objName = {string: null, ...}
Example:

{
"id": "07",
