Converting numbers into corresponding alphabets and characters using JavaScript
Problem
We are required to write a JavaScript function that takes in an array of numbers in string format. Our function must return a string. The numbers correspond to the letters of the alphabet in reverse order: a=26, z=1 etc.
We should also account for '!', '?' and ' ' that are represented by '27', '28' and '29' respectively.
Example
Following is the code −
const arr = ['5', '23', '2', '1', '13', '18', '6']; const convertToString = (arr) => { let res = ''; for (let char of arr) { if (Number(char) <= 26) { res += String.fromCharCode(123 - char); } else { if (char === '27') res += '!'; else if(char === '28') res += '?' else res += ' '; }; }; return res; }; console.log(convertToString(arr));
