square_every_digit.ts

// Welcome.In this kata, you are asked to square every digit of a number and concatenate them.

// For example, if we run 9119 through the function, 811181 will come out, because 92 is 81 and 12 is 1.

// Note: The function accepts an integer and returns an integer

export class Kata {
    static squareDigits(num: number) {
        return parseInt(num.toString().split("").map(x=> parseInt(x)**2).join(""));
    }
}

console.log(Kata.squareDigits(9119)); //811181
