Squares of a Sorted Array

My Solution

JavaScript

/**
 * @param {number[]} nums
 * @return {number[]}
 */

const sortedSquares(nums) => {
    const n = nums.length;
    let squares = Array(n).fill(0),
        i = 0,
        j = n-1;

    while (i < j) {
      if (nums[i]**2 < nums[j]**2) {
        squares[j-i] = nums[j]**2
        j -= 1
      } else {
        squares[j-i] = nums[i]**2
        i += 1
      }
    }
    squares[0] = nums[i]**2

    return squares;
}
