Power of Two

Problem statement​

Given an integer n, return true if it is a power of two. Otherwise, return false.

An integer n is a power of two, if there exists an integer x such that n == 2x.

Example 1:

Input: n = 1Output: trueExplanation: 20 = 1

Example 2:

Input: n = 16Output: trueExplanation: 24 = 16

Example 3:

Input: n = 3Output: false

Constraints:

  • -231 <= n <= 231 - 1
Follow up: Could you solve it without loops/recursion?

My solution​

/**
 * @param {number} n
 * @return {boolean}
 */
var isPowerOfTwo = function(n) {
    return Number.isInteger(Math.log2(n/2))
};
