Mapping array of numbers to an object with corresponding char codes in JavaScript

Problem

We are required to write a JavaScript function that takes in an array of numbers. For each number in the array, we need to create an object. The object key will be the number, as a string. And the value will be the corresponding character code, as a string.

We should finally return an array of the resulting objects.

Example

Following is the code −

 Live Demo

const arr = [67, 84, 98, 112, 56, 71, 82]; const mapToCharCodes = (arr = []) => {    const res = [];    for(let i = 0; i < arr.length; i++){       const el = arr[i];       const obj = {};       obj[el] = String.fromCharCode(el);       res.push(obj);    };    return res; }; console.log(mapToCharCodes(arr));

Output

Following is the console output −

[    { '67': 'C' },    { '84': 'T' },    { '98': 'b' },    { '112': 'p' },    { '56': '8' },    { '71': 'G' },    { '82': 'R' } ]
