Merge sort (merge sort), also known as two-way merge sort, refers to the process of splitting an array into a recursive order for each sub-array, and finally merging the rows into an ordered array. Merge sort is the perfect realization of the

Two-way merge sort:The core of the idea when the problem in Split, and recursive call to divide the method, so that the problem is divided into the atomic problem can not be divided, and then merge, from the realization of the atomic problem, the

First, the basic ideaMerge sorts, dividing the current sequence into smaller sequential sequences, and then merging them into larger ordered sequences, one after the other. In this case, several small ordered sequences are divided into a sequence of

Data types other than null and undefined are defined as objects in JavaScript, and variables can be defined using the method of creating objects, String, Math, Array, Date, RegExp are important built-in objects in JavaScript, and most of the
