How to use Array.map and JSON.parse In Javascript
Using Array.map and JSON.parse, the function converts each byte in the byte array to its corresponding character, joins these characters into a string, and then parses the string into a JSON object. This effectively transforms the byte array into a JSON format.
Example:
function byteArrayToJson(byteArray) {
let jsonString = Array.from(byteArray).map(byte => String.fromCharCode(byte)).join('');
return JSON.parse(jsonString);
}
let byteArray = new TextEncoder().encode('{"name":"John","age":30}');
console.log(byteArrayToJson(byteArray)); // {name: "John", age: 30}
Output
{ name: 'John', age: 30 }
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]
Output: w3wiki
There are different approaches to Convert Byte Array to JSON. Let’s discuss each of them one by one:

- 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.
