Introduction to Merge Sort

Hello, rookie coders!

Today, we are focusing on the mighty Merge Sort, a potent way to organize data. It's time to explore and code this technique in JavaScript. Imagine shuffling a deck of cards and then rearranging them in order. Merge Sort accomplishes exactly this with data, but on a grander scale, making it top-tier for large-scale data.

Understanding the Merge Process in JavaScript

First, let's build a merge() function in JavaScript. It merges two sorted arrays into a single sorted array. Think of it as combining two sorted stacks of cards into one sorted stack.

The merge() function above takes two sorted arrays (left and right) and combines them into one sorted array (resultArray).

Seemingly tricky, the code is very straightforward:
