Squared concatenation of a Number in 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 −
99
Then the output should be −
8181
because 9^2 is 81 and 1^2 is 1.
Therefore, let’s write the code for this function −
Example
The code for this will be −
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
The output in the console will be −
811181
