I am intending to introduce some of the most commonly used programming languages that gained popularity within the past few years. I have made a list below so everyone can quickly reference this for their next coding journey:
If you’re interested in Apple products and mobile app development, Swift is a good place to start. First announced by Apple in 2014, Swift is a relatively new programming language used to develop iOS and macOS applications.
Swift has been optimized for performance and built from the ground up to match the realities of modern iOS development. Not only does iOS run on every iPhone and iPad, but it’s also the basis for other operating systems such as watchOS (for Apple Watches) and tvOS (for Apple TVs). In addition, Apple isn’t going anywhere as a tech industry leader, and iOS apps continue to be the most profitable in the mobile app marketplace.
If you’re familiar with Java — a classic programming language in its own right — it’s worth checking out its modern cousin, Scala. Scala combines the best features of Java (such as its Object-Oriented Structure and its lightning-fast JVM runtime environment) with a modern twist.
As a functional programming language, Scala allows engineers to elevate the quality of their code to resemble pure math. Scala allows for concurrent programming, allowing complex procedures to be executed in parallel. Furthermore, it is a strongly typed language. Engineers can create and customize their own data types, allowing them to have the peace of mind knowing entire swaths of bugs are impossible at runtime.
One of the core languages favored by Google, Go is the little language that could. As a low-level language, Go is ideal for engineers who want to enter the field of systems programming. It encompasses much of the same functionality of C and C++ without the difficult syntax and steep learning curve. It’s the perfect language for building web servers, data pipelines, and even machine-learning packages.
As a compiled language, Go runs “close to the metal,” allowing for a blazing-fast runtime. It’s an open-source language, and ambitious developers can see their personal contributions adopted and enjoyed by programmers worldwide.
Python is perhaps the most user-friendly programming language of any on this list. It’s often said that Python’s syntax is clear, intuitive, and almost English-like, which, like Java, makes it a popular choice for beginners.
Also like Java, Python has a variety of applications that make it a versatile, powerful option when choosing the best programming language for your use case. If you’re interested in back-end web development, for example, then the open-source Django framework, written in Python, is popular, easy to learn, and feature-rich. Django has been used in the development of some popular sites like Mozilla, Instagram, and Spotify.
Python also has packages such as NumPy and SciPy that are commonly used in the fields of scientific computing, mathematics, and engineering. Other Python libraries such as TensorFlow, PyTorch, scikit-learn, and OpenCV are used to build programs in data science, machine learning, image processing, and computer vision. Python’s science and data applications make it a great choice for the academically inclined.
One of the youngest languages on our list, what began as a Harvard student’s thesis has now grown to become a point of passion for front-end developers around the world.
Furthermore, the Elm web architecture was the intellectual inspiration for Redux, the state-management library taught here at Fullstack.
Ruby is another scripting language that’s commonly used for web development. In particular, it’s used as the basis for the popular Ruby on Rails web application framework.
Beginners often gravitate toward Ruby because it has a reputation for having one of the friendliest and most helpful user communities. The Ruby community even has an unofficial saying, “Matz is nice and so we are nice,” encouraging members to model their kind and considerate behavior on Ruby’s chief inventor Yukihiro Matsumoto.
In addition to the active community and its straightforward syntax, Ruby is also a good language to pick up thanks to its association with great tech businesses. Twitter, Airbnb, Bloomberg, Shopify, and countless other startups have all built their websites using Ruby on Rails at some point.
Like C++, C# (pronounced C Sharp) is a general-purpose, object-oriented language built on the foundations of C. It was originally designed by Microsoft as part of its .NET framework for building Windows applications.
C# uses a syntax that’s similar to other C-derived languages such as C++, so it’s easy to pick up if you’re coming from another language in the C family. C# is not only the go-to for Microsoft app development, but it’s also the language mobile developers use to build cross-platform apps on the Xamarin platform.
Additionally, anyone who is interested in VR development should consider learning C#. C# is the recommended language for building 3D and 2D video games using the popular Unity game engine, which produces one-third of the top games on the market.
Rust is a bit of an upstart among the other languages on this list, but that doesn’t mean it’s not a valuable language to learn. Stack Overflow’s 2020 Developer Survey found that Rust was the most loved programming language among developers for the fifth year in a row, with 86.1 percent of Rust developers saying that they want to continue working with it.
Developed by the Mozilla Corporation, Rust, like C and C++, is intended primarily for low-level systems programming. What Rust adds to the mix, however, is an emphasis on speed and security. Rust emphasizes writing “safe code” by preventing programs from accessing parts of memory that they shouldn’t, which can cause unexpected behavior and system crashes.
The advantages of Rust mean that other big tech companies, such as Dropbox and Coursera, are already starting to use it internally. While it may be a bit more difficult to master than other beginner languages, Rust programming skills are likely to pay off handsomely, as the language’s popularity will only continue to rise in the near future.
