Top 10 Backend Development Languages

Application development typically consists of two parts. One is client-side, and the second is server-side development.

The Client-side serves the users. Indeed, they can witness all frontend operations. However, the server-side couldn’t be seen or approached by the users, and these are coders who deal with the backend.

To build ideal and interactive application software, selecting the right backend development language is as important as the frontend language.

So, this article will provide a detailed overview, advantages and limitations of the best backend development languages. These details would assist the developers and enterprises about what server-side language is the right match for their software.

What is a Backend?

Backend is comprised of the components of an application that the app users couldn’t access. This server-side code could only be operated by the developers. The backend script usually consists of one or more server-side programming languages and manages the databases and server-centric operations.

Python, JavaScript, PHP and Java are the notable backend development languages that coders can utilize for their projects.

Top 10 Backend Development Languages

Here are the top backend development languages with all essential details that are needed to shortlist the suitable languages.
