What is Backend Development?

All server-side operations and interactions between the browser and database are referred to as backend development. Servers, databases, communication protocols, operating systems and software stack are the core tools used in backend development.

JavaScript, PHP, Python, Java and Ruby are the known backend programming languages that most backend developers are using nowadays.

A survey of W3Techs claims that PHP is the most used backend language. Around 79.2% of web applications are using PHP as server-side applications.

On the other hand, Stack Overflow’s 2020 Developer Survey shares that JavaScript is the top most used scripting language. Indeed, JavaScript got 69.7%, Python earned 41.6%, and PHP received 25.8% votes from professional developers in this survey.

Types of Backend Programming Languages

Backend programming languages are usually categorized into two major types. We are going to discuss these types below!

  • Object-Oriented Programming

This backend development approach emphasizes object or data formations instead of using logic. With uncommon characteristics, the object is considered a data field in functional programming. The object-oriented programming technique is the best approach when developers work in teams on big and complex projects.

PHP, Java, Ruby and Python are the common examples of OOP backend programming. Regardless of many benefits, experts criticize OOP because of its complex scripting style. It also takes more time when it comes to assemble and write the code.

  • Functional Programming

It is another type of back-end programming focusing more on declarations and results than the programming procedure. FP backs parallel, immutable data and doesn’t have any side effects. So, FP is the answer if you want to improve productivity & modularity and to sort out scripting issues in the simplest ways.

SQL, R, Haskell and F# are the famous FB backend programming languages that you can consider using. On the contrary, this backend programming language also has some limitations. Practicing difficulty for beginners, complex maintenance and reuse are some major cons of using functional programming languages.

Top 10 Backend Languages

There are several backend programming languages that developers are using nowadays for their projects. However, we are sharing the most reliable and well-reputed top 10 backend languages here.

1. JavaScript

JavaScript is one of the most trustworthy backend programming languages. Coders use this language for both server-side and front-end tasks.

This backend language was initially launched 25 years back in 1995 and usually denoted as ‘JS’. Withal, you shouldn’t mix it with Java because both Java and JavaScript are completely different languages.

JavaScript offers many advantages, including rich interfaces, online availability of numerous resources and Interoperability. Moreover, it is also considered one of the most popular programming languages.

Undoubtedly, 69.7% of professional developers said they are using JavaScript for their projects, according to the 2020 Developer Survey of Stack Overflow. JS is holding this top position for the last 8 years in a row.

JavaScript Features

Dynamic Data Type — In JavaScript, data types of variables are not predefined. It indicates that you can reuse variables easily for any kind of data type. You can store any type of data in a variable, like if you have stored string “ABC” in variable x. Later you can store any integer or array in the same variable. It means that you do not need to declare an extra variable for another type of data where the previous variable is not being used. It helps in saving memory & improves coding practice, and reduces lines of codes as well.

Lightweight — JavaScript is a lightweight scripting language that is mostly used for data handling on the browser side. Programmers usually use this language for client-side execution which is the reason that it is fast and lightweight.

Async Processing — Async processing is one of the most useful features of the JavaScript language. Using JavaScript, a block of the script won’t be able to stop or let the other block of code wait for the response to get started. If a request is being processed, then others will also work in parallel with the previous request instead of waiting for the response for the previous request. It saves a lot of time by running scripts in parallel.

Divide Server Processing Load — JavaScript allows you to perform basic functionalities on the client-side. This means that the server will not have to process the basic functionalities that improve server performance.

JavaScript Limitations

  • JavaScript is not suitable for the development of networking apps.
  • Although it was designed as a lightweight coding language, but its weak language design becomes a headache in some cases.
  • Complex maintenance is also a con of using JS as a backend.

Programmers can use the modules in the classes which means those methods of the modules will be added to the class. It is similar to inheritance but easier and more flexible.

Naming Conventions — Ruby defines the specific naming conventions for variables, classes, etc.

  • The constants in Ruby should start with a Capital letter
  • A global variable must start with a dollar sign ($)
  • An instance variable should be started with @
  • A class variable should be started with double @ (@@)

These naming convention rules help the programmers to write and read with effective coding. It is more helpful when a team of multiple members working on the same project because understanding the code becomes easy with these naming conventions.

Dynamic Data Types — Ruby is a convenient programming language where data types should not be defined while declaring the variable. A variable can contain any kind of data that saves the memory & reduces the lines of code by not declaring different types of variables for different types of data. You can use a variable for any kind of data according to your program requirements without declaring multiple variables.

Ruby Limitations

  • The runtime speed of Ruby is comparatively slower to other languages. Surely, complex programs might take time to complete their execution when coders use Ruby.
