How to convert an ASCII character into a hex value in Node.js

Answer 1

function asciiToHex(ch) {
    // Get the ASCII value of the character
    const asciiValue = ch.charCodeAt(0);
    
    // Convert the ASCII value to a hexadecimal string
    const hexValue = asciiValue.toString(16);
    
    return hexValue;
}

const ch = 'z';

const hex_value = asciiToHex(ch);

console.log("The hexadecimal value of '" + ch + "' is 0x" + hex_value);

   
   
/*
run:
   
The hexadecimal value of 'z' is 0x7a
   
*/
