Top Programming Languages and Their Common Applications

Computer programming requires using different languages to achieve the designer’s goals. Languages are classified into different categories and application programming languages.

Computer languages are classified as low, middle, or high-level languages. The classification is based on how far abstracted they are from hardware. For example, Java is considered a high-level language.


Another way to categorize computer programming languages is the following:


These computer program languages use a series of commands or statements to reach a goal. The series of commands used forms the procedure. Java and C++ are two of the most common procedural languages. Others include PASCAL and Basic.


A functional computer language uses mathematical functions to achieve results. A code module performs a task where the result will vary depending on what a programmer puts into the function.

Functional languages are not as well known, including Erlang, Scala, F#, and Elixir.


An object-oriented language approaches a program by seeing it as a series of objects called attributes and methods. All objects can be repetitively used in the program. This makes it very useful when designing complex software and other programs, such as custom software applications for industry.

Java and Python are two of the most commonly used object-oriented languages.


Scripting languages are particularly useful because they are used for automated tasks that make websites flow well and help attract customers. Scripting languages are also used to support other languages and software platforms. Scripting languages include PHP, Ruby, Python, bash, Perl, and Node.js.


This type of programming language uses a series of facts and rules that the computer uses to make decisions. This is in contrast to programs that simply tell the computer exactly what to do. Common logic languages include Prolog, Absys, and Datalog.

Most common programming languages

As you can see, there are a lot of programming languages out there. Some languages are definitely more widely used than others. Here are a few examples of the programming languages you are most likely to use for any programming work.


Java is often used for developing Android applications. With so many smartphones and tablets using the Android operating system, Java is the most used computer language due to its immense versatility.

Java can handle a lot of requests without becoming incredibly slow. This is very important in a world where speed is of the utmost importance. If an app or software program cannot respond practically instantly, users will abandon it for one that does.


HTML or Hypertext Markup Language is often used to design and display webpages. If you are familiar with WordPress, then you are using a website design that is based on HTML languages. Many of the customizations that you can do in WordPress are accomplished by going into the HTML code. You can edit a WordPress blog post or webpage by switching to an HTML view that allows you to see the webpage as it appears in code. Embedding videos and other widgets is accomplished in HTML.


The Python computer programming language is used for a variety of tasks, including software development, webpage design, data analysis, and automation tasks. A good example of a Python application is recommendation algorithms such as those used to suggest purchases or what you should watch next on popular web streaming services.


HQL is the abbreviation for Hibernate Query Language. It is used to help connect databases to languages such as Java. It makes it easier to retrieve data sets and specific numbers and columns. Anytime there is a database involved, HQL can help connect it to the front end of software so that operations are smooth and flexible.


If you want a lot of control over Java then you may find that you need to use TypeScript. This programming language. The additional syntax it adds allows for better integration with editing programs.


Who uses programming languages?

Computer programming languages are essential for a wide range of professionals, not just those exclusively working in computer science. Individuals in fields such as data science, web development, artificial intelligence, and even finance rely on these languages to perform tasks and solve complex problems. Baylor University Online offers a Masters in Computer Science program that caters to both experienced professionals and newcomers to the field. 

If you have some experience with programming languages, you can complete your degree in around 18 months, making it an ideal choice for career advancement. Even if you are new to computer science, this program offers an efficient path to earning your degree in just over 2 years, all while allowing you to maintain your current job. Below is a list of professionals who use programming languages in their work to solve problems, automate tasks, and develop applications:

Computer scientists

Computer scientists use programming languages as a fundamental tool in their work to develop software, analyze data and conduct research. Part of the role of a computer scientist is to analyze large datasets to extract meaningful insights. They use languages like Python and R to process and manipulate data. They also use programming languages to conduct in-depth research and experiments, often aimed at resolving intricate challenges and advancing the discipline. Whether it involves simulating complex physical phenomena or modeling intricate biological processes, programming languages provide the necessary computational power.

Game developers

Programming languages are the fundamental tools that enable game developers to bring the imaginative and interactive worlds of games to life. They use languages like C++, C# and Python to define game mechanics, character behavior, graphics, and sound. These languages allow developers to implement player interactions, non-player character (NPC) behavior, and game physics, as well as manage game assets. Whether it’s crafting an epic adventure, a strategic puzzle, or a competitive multiplayer experience, programming languages are the building blocks upon which the entire gaming experience is constructed. 

Data analysts

Companies have long known the value of knowing their customer well. Now many are turning to data analysis to discover market trends and other information they can use to make better business decisions. Data analysts employ programming languages to process, analyze, and draw meaningful insights from large datasets. Languages such as Python, R, and SQL serve as the foundation for data manipulation and statistical analysis. 


Programming languages allow for massive amounts of innovation. Without them we would be unable to create the apps, games, software, and more that allows for modern life and provides a lot of our entertainment.
