Array

An array is a fundamental data structure in JavaScript that allows you to store and manipulate collections of data. It is an ordered list of elements, each identified by an index or a key, that can be of any data type, including numbers, strings, objects, or other arrays. Arrays are commonly used to store data that needs to be accessed or manipulated in a specific order or sequence. With arrays, you can perform various operations, such as adding, removing, or updating elements, sorting, filtering, and searching. One of the advantages of arrays is their flexibility and efficiency in handling large amounts of data. In JavaScript, arrays are dynamic, meaning you can add or remove elements as needed, and they automatically resize themselves. Overall, arrays are a powerful tool for developers to work with and are a key part of many JavaScript programs.
