What Is Backend Development? 


Web development activities at the back end of programs are referred to as back end development. Back-end development covers server-side web application logic and integration and activities, like writing APIs, creating libraries, and working with system components instead of frontend development, which focuses on customer-facing services and programs. Backend developers build code that allows a database and an application to communicate with one another. Backend developers take care of and maintain the backend of a website, including databases, servers, and apps, and they control what you don't see.

Now that you know what Backend Development is, look at the best backend languages in the market today.
