JavaScript Hex to String Conversion: A Simple Guide

To convert a hex value to a string in JavaScript, you can use the 'String.fromCharCode' method along with parsing the hex value using the 'parseInt' function.

Here's an example code snippet:

const hexValue = '48656c6c6f20576f726c64'; // Hex value

// Convert hex to string
const convertedString = hexToString(hexValue);
console.log(convertedString);

// Function to convert hex to string
function hexToString(hex) {
  let str = '';
  for (let i = 0; i < hex.length; i += 2) {
    let charCode = parseInt(hex.substr(i, 2), 16);
    str += String.fromCharCode(charCode);
  }
  return str;
}

In this example, the 'hexToString' function takes a hex value as input and converts it to a string using a loop. The 'parseInt' function is used to parse the hex value, and the 'String.fromCharCode' method is used to convert the parsed hex value to a character. The converted string is then returned.

Running the above code will output: 'Hello World'
