ASCII to hex and hex to ASCII converter class in JavaScript

Problem

We are required to write a JavaScript class that have to member functions −

• toHex: It takes in a ASCII string and returns its hexadecimal equivalent.
• toASCII: It takes in a hexadecimal string and returns its ASCII equivalent.

For example, if the input to the function is −

Input

const str = 'this is a string';

Then the respective hex and ascii should be −

74686973206973206120737472696e67 this is a string

Example

const str = 'this is a string'; class Converter{    toASCII = (hex = '') => {       const res = [];       for(let i = 0; i < hex.length; i += 2){          res.push(hex.slice(i,i+2));       };    return res       .map(el => String.fromCharCode(parseInt(el, 16)))       .join('');    };    toHex = (ascii = '') => {       return ascii          .split('')          .map(el => el.charCodeAt().toString(16))          .join('');    }; }; const converter = new Converter(); const hex = converter.toHex(str); console.log(hex); console.log(converter.toASCII(hex));

Output

74686973206973206120737472696e67 this is a string
