Function pow(x,n)

importance: 4

Write a function pow(x,n) that returns x in power n. Or, in other words, multiplies x by itself n times and returns the result.

pow(3, 2) = 3 * 3 = 9
pow(3, 3) = 3 * 3 * 3 = 27
pow(1, 100) = 1 * 1 * ...* 1 = 1

Create a web-page that prompts for x and n, and then shows the result of pow(x,n).

Run the demo

P.S. In this task the function should support only natural values of n: integers up from 1.

function pow(x, n) {
 let result = x;
 for (let i = 1; i < n; i++) {
 result *= x;
 }
 return result;
}
let x = prompt("x?", '');
let n = prompt("n?", '');
if (n < 1) {
 alert(`Power ${n} is not supported, use a positive integer`);
} else {
 alert( pow(x, n) );
}
