Square every digit of a number - JavaScript
We are required to write a JavaScript function that takes in a number and returns a new number in which all the digits of the original number are squared and concatenated
For example: If the number is −
9119
Then the output should be −
811181
because 9^2 is 81 and 1^2 is 1.
Example
Following is the code −
const num = 9119; const squared = num => { const numStr = String(num); let res = ''; for(let i = 0; i < numStr.length; i++){ const square = Math.pow(+numStr[i], 2); res += square; }; return res; }; console.log(squared(num));
Output
This will produce the following output in console −
811181
