Array concat()

In this chapter you will learn:

How to add array together

Append array

The concat() method appends one array to another.

When no arguments are passed in, concat() clones the array and returns it. If one or more arrays are passed in, concat() concatenate the those arrays. If the values passed in are not arrays, they are simply appended to the end of the resulting array.
