Converting a JSON Text to a JavaScript Object. A common use of JSON is to read data from a web server, and display the data in a web page. For simplicity, this can be demonstrated using a string as input. First, create a JavaScript string containing JSON syntax:
Use the JavaScript function JSON.parse() to convert text into a JavaScript object: const obj = JSON.parse('{"name":"John", "age":30, "city":"New York"}'); Make sure the text is in JSON format, or else you will get a syntax error.
This tutorial covers showing multiple examples of demonstration of datatypes and arrays and objects in JSON data with examples.

JSON stands for JavaScript Object Notation, and it's designed to store and transport data. JSON is designed to store and organize data similar to XML, but JSON is smaller, faster, and easier to parse than XML. This tutorial series will help you to get started in JSON.
JSON object literals are surrounded by curly braces {}. JSON object literals contains key/value pairs. Keys and values are separated by a colon. Keys must be strings, and values must be a valid JSON data type: string; number; object; array; boolean; null; Each key/value pair is separated by a comma.
Javascript's Number type (64 bit IEEE 754) only has about 53 bits of precision. But, if you don't need to do any addition or multiplication, then you could keep 64-bit value as 4-character strings as JavaScript uses UTF-16. For example, 1 could be encoded as "\u0000\u0000\u0000\u0001".
