Instructions:
You are going to be given a non-empty string. Your job is to return the middle character(s) of the string.
If the string's length is odd, return the middle character.
If the string's length is even, return the middle 2 characters.

Thoughts:

  1. I check the condition of the string to be even or odd: s.length % 2 === 0 2.Function of that I return 2 middle letters for even and 1 middle letter for odd.

Solution:

function getMiddle(s) {
 return s.length % 2 === 0 ? s.slice(s.length/2-1, s.length/2 + 1) : s[Math.floor(s.length/2)];
}
