Gone are the days when a web developer could do all the daily tasks using just one programming language. Now, the situation is completely different. If you want to get a better job or be up-to-date with the ever-changing technology trends, you must not stop learning new programming languages. Working in reputable development companies like Twinslash entails having multiple languages in your tech stack.

Expanding your tech skills means that you are versatile and flexible for the market changes. JavaScript and HTML/ CSS score the highest among the most used programming languages worldwide, with 65% and 55% of respondents utilizing them in their work. However, there are some other options worthy of your attention. Let’s review the top programming languages to consider learning now that will be in demand in the nearest future.

1. Python

Promising Programming Languages

Python is a general-purpose programming language that supports several programming methods, including functional, object-oriented, and structured programming. It is widely regarded as a perfect tool for beginners because of its simple structure and syntax. Experienced developers also find Python useful due to its scalability, GUI apps support, and integrations with other languages (JAVA and C++, for example).

Key Features

Python comes with an extensive library of commands and tasks. It also features interactive development, enabling programmers to test the code before deployment, which reduces the time wasted on reworking. It also does not obligate developers to compile the program before executing it.

Python is portable and interoperable as it is compatible with many platforms (Macintosh, Windows, Linux, etc.) It’s easily extendable by adding low-level modules and scalable due to excellent support and structure compared to shell scripting.

Besides, Python supports GUI applications that can be ported to most systems. It also has automatic garbage collection functionality and dynamic type checking support.

Why It Is Worth Learning

Python is the first choice for young developers. It’s intuitive enough, yet has great potential when it comes to fully-fledged projects. Knowledge of Python alone makes you good enough for most potential employers.

What You Can Create with It

Python is great for back-end development, AI/ML-based apps, IoT apps, serverless computing, etc. Just to mention, all major databases’ interfaces are Python-based. Some world-famous software solutions, such as YouTube, Google, Spotify, Netflix were developed using Python.

2. Solidity

Solidity is a contract-oriented programming language intended for working with smart contracts in the first place. Smart contracts serve as a means for storing programming logic transacted on the blockchain. Solidity borrowed a lot from Python and JavaScript. It’s designed for the Ethereum Virtual Machine hosted on Ethereum nodes.

Key Features

Solidity supports libraries and single/multi-level feature inheritance between contracts. It has the needed capability to build blockchain applications and write smart contracts that can further be used for voting, crowdfunding, or multi-sig wallets. Solidity supports common data types belonging to OOP, including Boolean, Integer, String, Modifier, and Array.

Why It Is Worth Learning

Currently, Solidity is the core language of Ethereum and some other private ledgers (SWIFT and Monax). Solidity is intended for developers involved with cryptography, blockchain operation, and smart contract creation — activities that continue to gain momentum in 2022.

What You Can Create with It

Solidity enables the incorporation of the smart contract system into software. Basically, this programming language enables you to create dApps using the EVM.

3. Swift

popular programming languages

Swift was created by Apple in 2014. It’s designed to work with the iOS ecosystem and OS X (macOS, tvOS, Linux, etc.) Swift is an open-source programming language, so you can port it to other platforms without any additional licenses or permissions.

Key Features

Swift has LLVM as the compiler, and it’s incorporated within Xcode — the IDE standard intended to work with the Apple ecosystem. This programming language supports inferred types that make code less prone to mistakes. Memory is managed automatically, and you can use protocol extensions to simplify writing generic code.

Swift enables concise iteration over a collection or a range. It has an advanced control flow and an error handling functionality built in.

Why It Is Worth Learning

Earlier, iOS-based apps were created using an Objective-C coding language. But now, Apple officially claims that Swift is to be used for all the new software solutions. So, every developer specializing in iOS applications should add Swift to their tech stack.

What You Can Create with It

Generally, Swift can be used to create native applications that fit the iOS ecosystem. Updates, improvements, technical support and maintenance of software are also performed with the help of Swift.

4. C#

C# is an object-oriented programming language developed by Microsoft in 2000 and has improved heavily since that time. C# is a general-purpose language that has grown in popularity among developers of web and desktop apps.

Key Features

C# is simple to use. There are no pointer types, does not allows unsafe operations, and features automatic memory management. This programming language is interoperable thanks to the native support for Windows-based apps. It’s also scalable and updateable since there is no registering of a dynamic linking library.

Why It Is Worth Learning

C# is a well-established programming language that has undergone improvements. It’s a modern solution for creating various solutions for the Microsoft .NET platform.

What You Can Create with It

It’s possible to develop Windows client apps, libraries, and components. Besides, it’s used to create backend databases using ML or AI. C# also enables the creation of fully-fledged gaming consoles and video games.

5. Kotlin

programming language

Kotlin is an open-source programming language that belongs to the family of statically typed languages. It combines functional and technical parts of development. Kotlin is compatible with JVM in the first place but works with JavaScript as well. Kotlin was influenced by other languages, including JavaScript, C#, and Scala.

Key Features

With Kotlin, you can create cross-platform apps, but it is highly preferred for Android development. This programming language is very concise since it considerably eliminates boilerplate code. It’s interoperable, scalable, and easy to use thanks to its similarity to the world-famous Java. As an extra benefit, Kotlin gives small runtime and better performance for apps.

Why It Is Worth Learning

Kotlin is a new language intended to complement Java. It’s been accepted as the official language of the Android development process, so Android developers cannot go without it.

What You Can Create with It

Kotlin is a great choice for cross-platform mobile apps, web development, Android development, server-side apps, desktop apps, and data science-driven software solutions. Android developers should consider adding Kotlin to their tech stack in the first place.

Final Note

Choosing the first programming language to learn is of utmost importance for beginning developers. If you are not sure what language you should be involved with, consider the type of apps you are most interested in developing in the future. Since blockchain and VR are in vogue these years, Solidity and C# sound like good starting points. Remember that polyglot developers have the edge over the competition — in terms of salary, reputation, and project difficulty. So, it’s in your best interest to learn at least two languages from the list above.
