You’ll also need to understand how web servers receive and process requests for web pages, how they store data, and at least the basics of how to keep them high-performing and secure. Java is another general-purpose programming language often used in the back-end of application development. It was built to be deployable across a wide range of environments and is flexible enough to support complex, high-performing software projects.

• It is an object-oriented programming language that also supports the functional programming paradigm.
• Learn about RESTful and GraphQL APIs to understand how applications communicate with each other.
• Backend developers will deal with only a handful of these, as there are many different sub-types, and more are created every year.
• Back-end developers build the core functionality of websites and apps.

What’s the role of APIs in back-end development?

But many of the websites you work on will have one or need to have one implemented. Backend developers are often called in to add new CMS features or debug an existing CMS. Java is a general-purpose programming language, and while it can run on a browser, it’s primarily intended for backend development. Python is a programming language that every backend developer should know. It’s used by major companies like Instagram, Spotify, and DropBox, and its popularity continues to rise. It’s also a good idea to have a basic understanding of core frontend skills like HTML and CSS.
