Top 10 Backend Languages You Should Know About

This article will discuss the best ten backend languages, their core features, advantages, and disadvantages.

Becoming a backend developer is very compelling! According to Indeed, the average backend developer salary in the United States is $121,875 per year.

According to GitHub’s State of the Octoverse 2020 Report, Javascript, Python, and Java remain the most popular backend languages worldwide.

Frontend technologies attracted a lot of attention, but it wouldn’t be possible with backend web development as the backend enables the frontend experience.

Whether it is about database interactions, performance, or setting the program or application’s logic, the backend is an integral part of programming.

If you are looking for the best backend web development, here are the top 10 backend languages highly valuable to developers.

What is Backend?

Backend in computing is a part of a software or website that is invisible to users. It is the opposite of the front end, which refers to a website or software user interface (UI).

While the frontend is referred to as the presentation layer, the backend serves as a data access layer.

Websites today are dynamic, and content is created spontaneously. Web pages consist of scripts, and every time a user accesses the page, the scripts run on the server.

They are responsible for displaying the content on the user’s web browser. Meaning, the processes that facilitate showing the content are part of the backend.

Here are some of the processes involved in the backend:

  • Storing records in a database.
  • Using SQL queries to access data from a database.
  • Management of uploading and downloading files.
  • Running a JSP, PHP, ASP, or similar scripts to generate HTML
  • Processing incoming webpage requests
  • Using JavaScript to process user input

Apart from the last point, all the other processes listed above are server-side processes running on web servers. You can consider JavaScript to be either a frontend or backend process based on whether or not the code has an impact on the UI.

Since it is a client-side process, it runs in the web browser. The user experience is the end product of the frontend and backend working together.

What is a Programming Language?

A computer programming language lets you provide instructions to a computer using a language designed to communicate with it.

Like the diversity in human languages, many computer programming languages exist, which programmers use to communicate with computers. Computers understand “binary” language, and when a programming language is translated into binary, it is called “compiling.”

From Python to C Language, each one has its unique set of features. However, there are usually many things common between them. Computer programming languages enable the devices to process a massive and complex amount of information efficiently effectively.

For instance, if a person is handed over 1 to 10,000 numbers in a randomized order and asked to arrange them in ascending or descending order, they are highly likely to take plenty of time and make many mistakes.

Why learn a backend programming language?

A backend programming language’s work is to handle the ‘behind the scenes’ functionality of Web applications. Its code assists in connecting the web to a database, offering virtual links, and powering the web app.

The backend development works together with the front-end to provide the finished product to the end-user. Here are some of the benefits of backend development.

  • Faster Information Sharing

The database, web server, and application comprise the most crucial elements of a website. When a user accesses the user interface of a website, they should be able to give their login ID and password; the runtime is used to check the user ID and password. Likewise, every piece of information submitted by the user is processed in the backend application.

Often, it retrieves information from the archive and sends the data to the web interface for viewing through the app. Therefore, the backend of a website works as its framework and allows the sharing of knowledge.

  • Functions in Various Environments

The majority of organizations launch web applications and websites in diverse environments. For example, some companies install online applications in the cloud, while others select websites functioning on database servers.

An increasing number of businesses today are combining all the hosting services to leverage enhanced scalability and capacity. How a Web server is set up depends on the network. Additionally, the programmers regularly disseminate workload server-side across many devices.

Due to the differing hosting environments, personalizing the website backend has become critical for developers.

  • Affects the User Experience of the Website

In the long run, the UI and accessibility of a website rely on its success. While the backend manages everything needed to enable a website’s functioning, the UI of a website is impacted by the backend technology’s reliability.

If there is an issue with the backend code, it can result in the website running slow, some performance-related issues, and even website crashing. Also, the minor loopholes in the backend code can lead to the website being defenseless against ransomware attacks.
