What is the JavaScript used for?
JavaScript is a programming language that is mainly used to create interactive effects within web browsers. It is a client-side scripting language, which means that the code is executed on the user’s computer rather than on the server. JavaScript is often used to create things like:

- Form validation
- Slideshows
- Games
- Interactive maps
- Video players
- Animations
JavaScript can also be used on the server side, for example with the Node.js runtime environment, but this is less common.
