JavaScript - Arrays

Javascript Arrays are data structures used to store an ordered list of values. Each value in the array is called an element and can be of any data type including numbers, strings, objects, or other arrays. Arrays are declared using square brackets [] and the elements are separated by commas. Arrays have a fixed length and their elements can be accessed using numerical indices starting from 0.

Arrays provide many built-in methods for manipulating their elements such as push to add elements to the end, pop to remove elements from the end, shift to remove elements from the beginning, unshift to add elements to the beginning, splice to add/remove elements at any position, sort to sort the elements, and reverse to reverse the order of elements.

Javascript arrays are dynamic in nature and can change their length at any time by adding or removing elements. This makes them an incredibly useful and flexible data structure in many applications.
