What is a Programming Language?

A programming language is a set of instructions that are written for a computer to execute. Computers only understand binary language that uses 1s and 0s. Programming languages bridge the gap between our language and the binary language of computers.

There are two different types of programming languages: high-level and low-level. Low-level languages are closer in nature to binary computer code. They're fast, efficient, and give you granular control. However, they can be hard for people to learn, understand, and read.

High-level programming languages more closely resemble human language. They're often easy to read and understand, even without extensive training. However, they take longer for the computer to translate and run than low-level languages.

With the advent of more powerful computers, the computational time difference between high-level languages and low-level languages has shrunk. In most cases, because high-level languages are easier to learn and the time differences are minimal, it's best to start by learning a high-level language.

12 Popular Languages for Programming 2022

There are a seemingly endless variety of popular programming languages to choose from in 2022. From building augmented reality experiences to banking applications and video game design, there's a language that's perfectly suited to what you want to do. Some are better for beginners, while others offer the fine-tuned control that experienced programmers are looking for. There's no one-size-fits-all option for choosing the best product.


JavaScript is one of the most often-used coding languages in the world due to its versatility, simplicity, and ease of use. Javascript is a scripting language that's used to control the behavior of web pages. Along with CSS and HTML, it makes up the triad of front-end programming languages. JavaScript is widely used in web applications, mobile applications, and game development.

You can use JavaScript to create dynamic web elements such as clickable buttons, interactive maps, and animated graphics. JavaScript works with HTML and CSS to give users a better web experience. It's easy for beginners to learn JavaScript because it requires no previous coding knowledge. You can test it out immediately in most browsers. There's a wealth of information available for learning JavaScript. You can join numerous online communities and access tutorials for help in learning JavaScript.


Python is a general-purpose programming language that can be used with different programming styles, such as functional, object-oriented, and reflective. Beginners are drawn to Python because it's easy to learn and has an extensive library of resources for plug-and-play use. Many well-known apps were built with Python, including:

  • Uber
  • Spotify
  • Pinterest
  • Dropbox
  • Instagram
  • Facebook

Python is extremely marketable in the IT industry. It's used for data science, machine learning, artificial intelligence, app development (including back-end applications), and more. Developers love the interactive nature of Python because they can test code as they go, meaning they don't need to invest copious amounts of time into creating long chunks of code that may later need to be revised.


Hypertext markup language — commonly referred to as HTML — is a markup language rather than a programming language. A markup language uses tags to define elements within a document as opposed to a programming language, which is used to produce output. HTML is one of the easiest languages to learn and is often a developer's first step in learning computer languages. It's used in creating web pages. It tells a browser where and how text should be displayed on a web page.

It doesn't have the same type of functionality as other programming languages, but it's invaluable in structuring web pages. HTML is used in over 90% of web pages, so it's a must-know if you're interested in front-end web development.


CSS, which stands for Cascading Style Sheets, is a design language that governs the look of a website. It allows developers to apply a style to a parent group and have it carry through all child groups throughout the site. This saves a tremendous amount of time since you can write CSS once and reuse it multiple times. Similarly, it's easy to maintain CSS by making changes to the style and applying it to all elements.

CSS has a much wider variety of styles than HTML, and the style sheets can be used to optimize content on many different devices. Your code is more efficient in CSS than in HTML. You don't have to include an HTML attribute at every instance, so there's less code to run, which makes for faster execution.


Java is a general-use, class-based, object-oriented programming language. Object-oriented languages allow you to create objects that hold data and functions that can then be used in programs. Java works exceptionally well for handling data and providing security. It's often used in the financial industry and for e-commerce applications.

Java uses simple syntax that's easy to learn, so it's beginner friendly. One of the top benefits of Java is that it's a write-once, run-anywhere language. It doesn't matter what operating system you use to write a Java program — it can run on any other operating system. This feature makes it ideal for writing apps for remote sensors and processors, apps, and other consumer devices with varied operating systems.

There are numerous resources and a robust support community for Java, so if you're trying to learn Java, you'll have lots of support. Java is in high demand as a programming language. There are currently over 100,000 jobs listed for Java developers.


SQL (Structured Query Language) is a programming language that is used to access and perform operations on the data stored in relational databases. It's used by database administrators, developers who are writing data integration scripts, and data scientists who are running analytical queries. SQL can locate, retrieve, and manipulate data to create sales reports and business management information.

Relational databases that work primarily with SQL are table-based. However, SQL is best used with smaller databases since it doesn't handle larger ones as well. In the era of big data, SQL is a valuable language to learn. Data analysis is a primary function of almost every organization.


NoSQL (Non-relational Structured Query Language) is used with non-relational databases. Non-relational databases store data in document, key-value, wide-column, or graph formats. NoSQL works with unstructured data and is suitable for delivering highly responsive experiences to many distributed users. Since 80% to 90% of data is unstructured, NoSQL is an extremely useful language for extracting information from otherwise impenetrable walls of unstructured data.

More companies are using NoSQL as digital economy trends increase both the availability of big data and the need to manipulate it. Some of these challenges include:

  • Customers increasingly going online
  • More connectivity
  • More data availability
  • More cloud-based applications
  • Increased use of mobile devices


C# (C Sharp) was developed by Microsoft to run on the .NET framework in 2002. It's a general-purpose, object-oriented language that was created as an improvement on C++. If you're experienced with any of the other C languages, you'll have an easy time learning C#. It's a versatile language that can be used in a variety of applications. C# is a popular choice for video game development for PCs and video game consoles. Types of games that have been created with C# include:

  • Platforms
  • Side-scrollers
  • Role-playing games
  • Augmented reality games
  • Virtual reality games

C# is obviously a favorite of Microsoft developers since it was designed to work with the .NET platform. However, it can also be used with an open-source platform as well. It's a statically typed language that's easy to read and understand. As it's been around for a while, there's a large community of developers and resources to support you as you learn it.


Go was developed by Google in 2007 as a way to write simple and efficient code. It's a minimalist language that's easy to learn. While there are add-ons for Go, the built-in frameworks for profiling and testing are fully functional and intuitive. It's a good choice for web development, cloud applications, DevOps and site reliability, and command-line interfaces.

With a dedicated networking API, Go has networking programming built into its standard library. Go can execute several processes concurrently, making it extremely efficient. It's also one of the fastest back-end programming languages available. Although Go is growing in popularity, it's not on the level of some of the more established languages yet.


Kotlin is another statically typed language that's easy to read and write. It's become popular with Android developers. It has many tools and frameworks that are compatible with Java, making it a viable option for many developers. Kotlin is much simpler than Java and other robust programming languages, allowing you to accomplish the same tasks with simpler and shorter code. Kotlin's simplicity makes it easy to read and understand. It also maintains Java's robustness due to its interchangeability. While Java is an established, beloved language, it's not without its flaws. Kotlin addresses many of these flaws while being more usable.


R is a simple, effective language designed for statistical computing and graphics. If you're running a data science project, R is likely to be the best option. It includes a wide variety of statistical and graphical techniques such as:

  • Linear and nonlinear modeling
  • Statistics tests
  • Time-series analysis
  • Clustering
  • Classification

R can easily produce well-designed plots that are ready for publication. It's a language that was designed for statisticians. Its functionality may be limited in that manner, but it does what it does very well.


Rust ranks well below some of the other languages in current usage, but it scores high on interest. Its advantages aren't as well known as some of the more popular languages such as Java and Python. Rust is multi-paradigm, which means you can work in a variety of programming styles with Rust. It's often used to create operating systems, virtual reality, and web browsers. It can run multiple concurrencies, making it a good choice when you need speed and efficiency. Rust also enforces memory safety so all references point to valid memory. If you're interested in learning an underused language with lots of possibilities, Rust is a great option.
