Learning JavaScript Data Structures and Algorithms

References for JavaScript array methods

Arrays in JavaScript are modified objects, meaning that every array that we create has a few methods available to be used. JavaScript arrays are very interesting because they are very powerful and have more capabilities available than the primitive arrays of other languages. This means that we do not need to write basic capabilities ourselves, such as adding and removing elements in/from the middle of the data structure.

The following is a list of the core available methods in an array object. We have covered some methods already.

Method	Description
concat	Joins multiple arrays and returns a copy of the joined arrays
every	Calls a function for every element of the array until false is returned
