alien road codeWho is a Back-End developer, what does he do, what programming languages does he use? In this guiding article for Back-End developers, we will examine the most popular programming languages.
Who is Back-End Developer?
Back-End developer, as the name suggests, is a back-end developer. Python, Asp.Net, C#, C++, Php, Ruby etc. He is the person who develops server-side applications using programming languages.
The backend developer ensures that the system runs responsively and quickly. For example, the back-end developer is the person who makes the coding that will list the relevant results for the keyword typed in the search bar on the website or send the relevant content by e-mail when you click on the contact form. In other words, a dynamic site with a management panel that is constantly changing and updated in real time gains functionality thanks to the back-end developer.
What Does a Back-End Developer Do?
After the Front-End developer develops the front end, he writes the code that makes everything work and is not directly visible to the user.
For example, a front-end developer creates the final payment page for products added to the cart on an e-commerce site. The Back-End developer, on the other hand, carries out the sales transaction through bank or intermediary payment channels via API services with the credit card information entered on the payment page.
Back-End developer needs more working time compared to front-end developer. Depending on the scope and size of the application, producing algorithms to establish the system architecture and solving problems are tasks that will take time.

A good back-end developer knows how to use libraries, how to integrate these libraries into his own system, and how coding and business logic are structured to facilitate the maintenance of the system.
If you enjoy designing the infrastructure of an application, building algorithms and working with data, you will probably enjoy working as a back-end developer.
Back-End Developer Getting Started Guide
Before moving on to the technologies and programming languages used by Back-End developers, there are some basic things you need to know.
1. It is necessary to know what the server, also known as the client-side, is and to have knowledge of the working logic of different types of servers.
2. It is necessary to know what a database is and which type of database is used in which field. Different databases are used for different programming languages. For a back-end developer, it is necessary to have a good understanding of the database, which is the second most important issue after the server.
3. It is necessary to know and understand what the HTTP protocol is, how it works, and how communication between client and server occurs.
4. It is necessary to know what API (Application Programming Interface) is and how to use it. It is extremely important to understand SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) services and know the differences between them.
The topics I mentioned above have extensive content with important details, with branches within themselves. You can use Google search results for an introduction to relevant topics and detailed information. I will discuss such detailed issues in the future.
It would be wrong to say that a successful back-end developer means a person who knows the HTML, CSS and JavaScript client languages in the front-end developer section. While doing research, I came across this type of definition very often. You can be a successful back-end developer without knowing the front-end side. But, like many people, I think that it would be beneficial for a back-end developer to know the basic client languages used on the front-end side, and that it would contribute to him financially and career-wise.
If you want to have detailed information about Front-End developer, this article can be a good start.
Which Programming Language?
Based on statistical data on which programming languages are most searched as of 2018, this topic is addressed in order to facilitate the back-end developer in making an informed decision in this difficult process.

A software developer considers the contribution of the programming language he will learn to his career and salary. At the same time, he constantly searches for an answer to the question of what is a programming language that is easy to learn, enjoyable to work in, promising and has plenty of job opportunities. I think you will have found the answer at the end of the article.
After giving a brief introduction about the increasingly popular programming languages, I will share statistical data according to the TIOBE index developed by TIOBE Company and updated monthly, average salaries from the Indeed employment search engine, and Google Trends data of the last 5 years.
Python
According to data published by TIOBE, the most popular programming language of 2018 was Python. It was found that Python’s popularity increased with approximately 5,000 job postings in 2018.
Python is a language that is easy to read and understand. It is also used by big brands such as Google, NASA, Wikipedia and Reddit is written in Python language.

has made a significant contribution to the popularity of the Python language. Django and Flask are becoming more popular thanks to their web framework structures.
With the increase in developing technologies such as artificial intelligence, machine learning, data mining and predictive analytics, experts who have full command of the Python language are in high demand.
According to 2018 stack overflow data, Python ranks first in the most searched languages analysis.
United States: Average annual salary for Python developers is $116K. That’s $9.6K per month.

JavaScript
JavaScript is a programming language that has the potential to develop applications in both client and server side areas.
While you develop client-based applications with React.js, Angular.js, Vue.js, Ember.js, Backbone.js, you can develop server-side applications with Node.js, thanks to the JavaScript programming language.
It is possible to indirectly create HTML and CSS integrated web pages with JavaScript language and develop mobile applications thanks to tools such as React Native and Apache Cordova.
• According to 2018 stack overflow data;
• As a result of programming, script and markup language analysis, JavaScript ranks first as the most popular language.
• The first three popular frameworks, libraries and tools are all based on JavaScript.
United States: Average annual salary for JavaScript developers is $110K. That’s $9.2K per month.
JavaScript 5-year Google Trends report.
java
Java is arguably the most popular language, used by millions of developers on billions of devices worldwide, and used by 90% of Fortune 500 companies, mostly on the back-end side.
Since it is a simple and readable language, I agree that it is a good choice for beginners. Since there are so many Java programming jobs available all over the world, Java is the one programming language you won’t be wondering if you can find a job in.
United States: Average annual salary for Java developers is $102K. That’s $8.5K per month.
Java 5-year Google Trends report.
C++
C++ is an object-oriented programming language developed to overcome the shortcomings of the C programming language. It provides better data security than the C programming language.
The syntax is complex and the learning level is difficult for beginners.
United States: Average annual salary for Java developers is $115K. That’s $9.6K per month.

If you are new to the Back-End side, you can start with any of the languages above and learn other languages over time. However, it is important to start with the language that suits your goals.
