Java Script is a high-level, dynamic, and interpretive programming language that was first created in 1995 by Brendan Eich. It is primarily used for creating interactive and dynamic web pages, but it has also been used to create desktop and mobile apps, games, and more.
One of the key features of JavaScript is its ability to run directly in web browsers, which allows for the creation of dynamic and interactive web pages. It can be used to create a wide range of features such as form validation, image sliders, pop-ups, and more. Additionally, JavaScript can also be used in combination with other web technologies such as HTML and CSS to create rich, interactive user interfaces.
JavaScript is also a versatile language and can be used for both front-end and back-end development. For front-end development, JavaScript can be used to create interactive user interfaces and to make web pages more dynamic. For back-end development, JavaScript can be used to create server-side scripts that can interact with databases and perform other server-side tasks.
