Approach

Swap and unswap

Implementation

1/**
2 * @param {string} s1
3 * @param {string} s2
4 * @return {boolean}
5 */
6var areAlmostEqual = function (s1, s2) {
7  s2 = s2.split("")
8  for (let i = 0; i < s2.length; i++) {
9    for (let j = 0; j < s2.length; j++) {
10      ;[s2[i], s2[j]] = [s2[j], s2[i]]
11      if (s2.join("") === s1) {
12        return true
13      }
14      ;[s2[i], s2[j]] = [s2[j], s2[i]]
15    }
16  }
17  return false
