In any case, IT specialists select technologies and tools individually based on the requirements of the project being developed. Thus, you receive the product most corresponding to your wishes.

The choice of programming language may depend on the speed, quality, and functionality of a future digital solution. Lampa Experts put together the best back-end languages in 2023, which have established themselves in the IT community as reliable assistants in project development. Check out our list to see which is right for your project.

What is Back-end Development?

Back-end development is part of a web app that is “invisible” to users. It is responsible for sending data to the server and their subsequent processing. It acts as a bridge connecting the database with the external interface of your digital product and takes care of fulfilling requests, downloading information, sending messages, and so on. All work on the product’s server side is performed by a back-end developer.

In addition to the languages ​​needed to create the app’s server side, specific back-end frameworks are used. These are software platforms with ready-made sets of tools that help specialists speed up work on projects. To choose the most suitable framework and the best language for back-end development, it is important to accurately convey to the developers the purpose of implementing your idea.

The IT team should understand why and for whom the app is being created, what functions it should perform, for which devices it will potentially be used, etc. Based on the outgoing order data, specialists also add tools to the technology stack to develop visual parts of a web solution called the front-end part. 

Back-end vs. front-end development: concepts and differences

Front-end and back-end may seem similar for people who are not familiar with the development of digital products. In practice, these are two different types of work when creating a program.

Front-end development means building a user interface. In other words, everything that users see when they open a website or web app: buttons, links, banners, fields, animations, and so on.

Let’s consider the key differences in working with the front-end and back-end of a digital solution:

Front-end development

Back-end development

Responsible for client-side – visual elements and their placement in the application.

Responsible for server-side – work with databases.

Used for building user interface and UX design.

Used for building the logic and functionality of the product’s internal part.

Focused on simplicity and ease of use.

Focused on efficient processing, management, and storage of data.

Provides high compatibility with different browsers and devices.

Provides scalability and high server-side performance.

Includes development of layouts and prototypes of a future web solution.

Includes API installation to connect all parts of a web application.

Types of Back-end Programming Languages

The classification of programming languages ​​is quite extensive. Let's look at the main types:

  • Object-oriented programming (OOP). The languages ​​of this group are based on the consideration of the program as a collection of objects that combine data and actions performed with them into one working program. OOP languages include Java, Python, C++, Ruby, C#, and JavaScript.

  • Functional programming (FP). In this kind, processes are presented like math-like functions. They are used to perform all calculations implemented in the code. FP representatives are Erlang, Haskell, F#, and Racket.

There is another classification:

  • Compiled. The machine independently translates the written program into machine code. This group includes C, C++, Erlang, Golang, etc.

  • Interpreted. To translate a written program, an additional tool is required – an interpreter, which facilitates the work of a programmer. Python, PHP, Ruby, and Perl are considered interpreted.

Languages are also divided by the level of use:

  • High-level – close to human language, so they are easier to understand and study. Good examples: JavaScript, Python, and PHP. They are widely used to write desktop and mobile applications, web services.

  • Low-level – machine languages like Assembler. They are mainly used in the development of operating systems and device drivers. Needed for coding virtual or real processors and designating machine instructions.
