How to use TextDecoder In Javascript
TextDecoder is a JavaScript object that converts byte data, like those in byte arrays, into strings using specified character encodings, aiding tasks such as parsing or displaying text-based content.
Syntax:
let textDecoder = new TextDecoder();
let result = textDecoder.decode(arr1);
Example: In this example, the TextDecoder object is used to decode the byte array into a string,
let arr1 = new Uint8Array([71, 101, 101, 107, 115]);
let textDecoder = new TextDecoder();
let result = textDecoder.decode(arr1);
console.log(result);

JavaScript Program to Convert Byte Array to JSON
In this article, we are going to learn about the conversion of a Byte Array into JSON. Converting a byte array to JSON means transforming a sequence of bytes into a structured JSON format, often involving decoding bytes to a text string and then parsing it into JSON data.
Example:
Input : [71, 101, 101, 107, 115, 102, 111, 114, 71, 101, 101, 107, 115]

- Using TextDecoder
- Using String.fromCharCode() Method
- Using for loop
- Using Array.map and JSON.parse
We will explore all the above methods along with their basic implementation with the help of examples.
