Description

Arrays plays a major role in JavaScript to learn all the useful methods in array then do watch this course. In this course we will cover all the useful methods, we will learn that how to add elements, how to remove elements, how to loop through an element, how to search an element, how to filter an element, how to slice an element from an array.

Some information about Array in JS:

The Array object, as with arrays in other programming languages, enables storing a collection of multiple items under a single variable name, and has members for performing common array operations.

In JavaScript, arrays aren't primitives but are instead Array objects with the following core characteristics:

JavaScript arrays are resizable and can contain a mix of different data types. (When those characteristics are undesirable, use typed arrays instead.)
JavaScript arrays are not associative arrays and so, array elements cannot be accessed using arbitrary strings as indexes, but must be accessed using nonnegative integers (or their respective string form) as indexes.
JavaScript arrays are zero-indexed: the first element of an array is at index 0, the second is at index 1, and so on — and the last element is at the value of the array's length property minus 1.
JavaScript array-copy operations create shallow copies. (All standard built-in copy operations with any JavaScript objects create shallow copies, rather than deep copies).
