Programming is one of the most popular and money-making disciplines in recent years. This field has many applicants due to its application in various professions and industries, and even many people who do not have a degree in computer science are interested in learning programming. The first step in starting programming is to understand the different domains and languages ​​used in each domain. In the following, we will get acquainted with different languages ​​and areas of programming.

Mobile domain programming

Mobile programming is a lucrative business. You can implement your ideas or work as a freelancer or hire for other people. If you are interested in mobile programming, you need to choose the platform you want before you start learning. Android and iOS are two popular mobile platforms that occupy a high percentage of the mobile market, and to write applications for each of these two platforms, you must learn its specific languages.

Android programming languages

Android operating system is developed and supported by Google. Common languages for developing Android applications are:


Java is an object-oriented language and is very similar to C and C ++. One of the important features of Java language is that it is multi-platform. This means that you can use this language to write programs under mobile, Windows, Linux, etc.


Kotlin is an object-oriented, static-type language, meaning that the type of variables is specified when compiled. Kotlin is known as the second language of Android development. This language is very similar to Java. Kotlin and Java code can be converted to each other. Kotlin is faster than Java and has shorter code.

IOS programming languages

IOS developed by Apple. Common languages for iOS app development are:


Objective-C is an object-oriented language that has been used in the past to develop software for Apple products. However, this language is still used by developers and has its own fans. If you have experience programming with an object-oriented language, it will be very easy for you to learn this language.


Swift is an open source, secure, flexible, and easy-to-use language designed to develop applications for Apple products. Swift is a modern language and an alternative to Objective-C. One of the key features of the Swift language is automatic memory management, which prevents common programming errors. In addition, both of these languages are compatible with each other and can easily work together, thus reducing project risk.

Cross-platform application development

Cross-platform applications are applications that run on different operating systems. Cross-platform application development helps reduce the cost of developing applications as well as saving time. Common programming languages used to develop cross-platform applications include:

React Native

React Native is an open source UI framework for building mobile applications offered by Facebook. With the help of React Native and JavaScript language, we can develop applications that can be run on various platforms Android, IOS, Web and even UWP (a platform for building applications under Windows, Windows Mobile, Xbox and other Microsoft products). React Native lets you develop mobile applications in JavaScript; React converts this code into Native language and gives you Android and IOS output.


The Flutter open source framework, developed with the Dart programming language, allows you to build applications that run on both Android and iOS platforms. Flutter was developed by Google, and the company is currently working on a new operating system called Fuchsia, in which you must master darts and flutter to develop its applications. Learning to work with the filter is easy and you can easily create great applications.

Desktop domain programming

Desktop programming is divided into two parts: software development under Windows and under macOS. Desktop applications require more time and resources to develop and are usually more expensive than other types of applications. In the following, we will introduce you to the most common programming languages under Windows and macOS.

Programming languages for software development under Windows:

  • C#
  • Java
  • JavaScript
  • C++

Programming languages for software development under macOS:

  • Swift
  • Objective-C

Web programming

With the increasing use of the Internet by users, the desire to use web-based software has increased. Web programming is divided into two parts: Front-end programming and Back-end programming. The front-end section is where users interact. The back-end is also divided into three sections: server, main program and database. The section where processes and processes are performed is not visible to users. A person who is proficient in both developmental skills and front-end is called a full-stack programmer in web design.

In the following, we will introduce you to the common languages to be used in both sections.

Front-End Section Languages:

Back-End languages(Server side):

  • PHP
  • Python
  • Ruby
  • NET
  • JavaScript
  • Perl
  • Java
  • GO
  • SQL
  • Scala
  • F#

Programming languages in the field of data mining, artificial intelligence and machine learning

Artificial intelligence is a relatively new and popular field in the field of computers that aims to develop programs and build machines that act intelligently like humans and contribute to the comfort and well-being of humans. Artificial intelligence has come to the aid of humans in various fields such as e-commerce, industry, medicine, agriculture, economics, etc.

Machine learning is one of the subsets of artificial intelligence. Machine learning algorithms enable machines to learn new things automatically and use what they have learned, just like humans, through various methods such as gaining experience, following instructions, and so on.

Today, companies provide a lot of information through the provision of services and continuous communication with the customer, which can use data mining techniques (Data Mining), to discover the hidden patterns within this data and use the results to improve the performance of the organization and the well-being of their customers.

Popular programming languages for working in these three areas are:

  • Python
  • R
  • F#
  • Prolog
  • Julia
  • GO

Development of computer games

Computer games are very popular among children, teenagers and even adults. Some people in developed countries make money by playing. Some people prefer to make unlimited income by developing computer games.

To develop computer games, you need to learn a programming language such as C ++, and you should also be familiar with scripting and game engines (such as Unity, Unreal, Game Maker, etc.).


Programming is a widely used and popular field that has been able to find its place in all areas of human life. You can find the field you are looking for by studying different areas of programming and discovering new needs, and then start earning money after learning the languages and skills you need.
