How to implement merge sort in JavaScript?

Posted by Prem Tiwari | Updated on

In this answer, I have shared how to implement merge sort in JavaScript.

Merge Sort Algorithm

  1. Divide the unsorted list into n sublists, each containing one element. A list of one element is inherently sorted.
  2. Repeatedly merge sorted sublists (called “runs”) to produce longer runs until there is only one run remaining. This is the sorted list.
