JavaScript
JavaScript is a scripting language for creating interactive and dynamic web pages. It is integral to modern web development and can be used for server-side and client-side scripting. JavaScript’s uses include web applications and development, mobile applications, games development, client-side validation, animated elements, and drop-down menus.
Server-side scripting using JavaScript is used on the server side of a browser and was popularised with the introduction of Node.js, a runtime environment that allows work on the server side.JavaScript is a single programming language that handles multiple operations. Even though it doesn’t directly help to make HTTP requests, RESTful APIs serve to make the client requests. Some other server-related functions include interaction with the databases and building applications like online games, live chats, and collections of small and independent services.
Client-side scripting, on the other hand, is implemented on the user’s browser and changes the elements and behaviour of web pages. The client side includes the following;
- Manipulation of HTML and CSS through Document Object Model(DOM).
- Bringing animated features by controlling CSS.
- Checking on user events like their clicks and creating interactive elements like dropdown menus and modal windows.
- Creating communication with the server for fetching data to enhance the user experience.
- Efficient data storage, like cookies or local storage, saves data from various sessions.
