JavaScript Add trailing numbers to integers in JavaScript

For example digits=4 means if input is 7 need output 7999, for 83 output should be 8399, for 9 output should be 9999. Want to add trailing 9 based on digits

Answer:1

You could take the stringes number and pad the needed values.

function nines(value, digits) {
    return +value.toString().padEnd(digits, 9);
}

console.log(nines(83, 4));
Answer:2

One thing you may be able to do is to multiply the input number by a power of 10 in order to add extra digits of 0 to the end, and then use addition to add 9 into each of those newly created digits.

For example:

Input - 7

7 * 1000 -> 7000 (NOTE: 1000 is a power of 10: 10^3)

7000 + (100 * 9) + (10 * 9) + (1 * 9) = 7999

Input

83 * 100 -> 8300 (NOTE: 100 is a power of 10: 10^2)

8300 + (10 * 9) + (1 * 9) = 8399
