JavaScript is a popular object-oriented programming language, which allows you to create interactive web pages. It enables dynamic updating of content, clickable buttons, and multimedia. It can be used on both the server-side and client-side of a website. In contrast, HTML and CSS are used to structure and style web pages, but JavaScript adds interactive elements that make them interactive. Without the use of JavaScript, 90% of all Internet webpages would be static.

In JavaScript, objects are standalone entities that hold values of properties and methods. An object property represents a literal value, while a method represents a function. Objects can be created with the object constructor and the object literal syntax. Arrays and objects are not the same thing, though. Arrays have a 0 index, whereas objects don’t. An array is useful for storing form input, while objects are best for holding numbers and strings.
