A JavaScript library, such as Express.js, is another way to get started. There are numerous approaches to learning JavaScript for backend development, but one of the simplest is to use a framework like Node.js. Getting started with JavaScript for the backend As JavaScript is compiled and executed on the server, it does not need to be downloaded and interpreted by the browser. Because it is event-driven, JavaScript is very scalable and can handle a large number of events (requests) without slowing down.īackend development requires speed. Scalability refers to a system's ability to handle increased load. This is ideal for backend development because it allows the server to handle multiple requests at once without having to wait for each one to complete before proceeding to the next. JavaScript has a lot to offer backend developers, thanks to its asynchronous nature, scalability, and speed.Īsynchronous programming is a type in which the program does not wait for one task to finish before moving on to the next. Express.js and Koa.js are two other preferred JavaScript frameworks. Since it is lightweight and efficient, Node.js is popular for backend development. It is a cross-platform environment built on the V8 JavaScript engine and includes a plethora of libraries and tools to help developers create powerful applications. It was introduced in 2009 so that JavaScript could run server-side applications. Node.js is a JavaScript runtime environment that allows JavaScript code to be executed outside of a web browser. This code is in charge of an application's server-side logic, including database interactions.

The frontend is what the user sees and interacts with while browsing the web. The server side of web development where you, the developer, write code to power the web application, is referred to as backend development.
