Picking the Right Programming Language: A Developer’s Guide

“What language should I learn?” This is a common question among aspiring or experienced software developers. Regardless of whether someone has a background in computer science or not, everyone asks that question at some point in their quest to acquire a new hat in programming. Over the years, judging from my experience, I have come to realize that certain factors are crucial in getting suitable answers to that question. Ideally, what we intend to build and the specific problems we aim to solve should naturally guide us toward the right programming language or stack. But, in the multitude of languages, frameworks, and new versions being churned out every other month, it’s understandable why this question is valid and not naive. Choosing the right tools and languages for a project is as crucial as the actual coding itself.

Web development is probably the most common field in which programming languages come into play. Website architecture is generally divided into frontend and backend development. The frontend is the part of the website which the end users interact with – the buttons you click, the text you read, and the visual layout of a website. The front end is often built with HTML, CSS, and JavaScript. While the first two are not actually programming languages, HTML is required to create the structure of a web page, and CSS is required to add aesthetics, with JavaScript providing the logic that powers the website. In order to be a frontend developer, one of the languages that should certainly be at the top of your list is JavaScript. It’s the engine that brings web pages to life. However, in modern development, relying on vanilla JavaScript, CSS, and HTML might not always be enough. Frameworks like React, Angular, and Next.js have emerged to streamline and optimize website architecture.

React, for example, is a popular JavaScript library for building user interfaces. I used it extensively in my projects, including Afrikapp, a freelance platform I built. Next.js, which is built on top of React, adds even more capabilities, such as server-side rendering, making it ideal for creating fast and dynamic websites. In contrast, Angular is a more comprehensive framework often preferred for building large, enterprise-level applications. However, it comes with a steeper learning curve compared to React. Companies like Upwork use Angular to handle the complexities of their platform in the front end.

There are several powerful languages to consider for the backend - the invisible part that handles databases, user authentication and more. Node.js, which I used in Afrikapp, is a JavaScript runtime environment that allows developers to use JavaScript for backend development, making it a full-stack language. PHP, a widely used language for backend development, powers many web applications today, especially with the Laravel framework. Laravel is favored for its elegant syntax, built-in features like authentication, and ease of managing database migrations. Python, with its Django framework, is another strong contender for building backends, especially because of its simplicity, readability, and large community support. Java is also used for backend development and is known for scalability and security, especially with the Spring Boot framework. It is a favorite among big organizations with massive enterprise applications.

Then there’s Go (aka Goland), a language designed for concurrency and multithreading. If you’ve ever interacted with platforms like Docker or Kubernetes, you’ve already encountered Go in action. It’s built for performance and is highly efficient when handling tasks where multiple things can happen simultaneously. For example, consider two people trying to update the same file simultaneously without causing any conflict in the database - this is concurrency at work. Or think about watching a YouTube video while commenting and downloading the video all at once - that’s multithreading. Go is perfect for handling these complex tasks, and it’s often chosen for high-performance backend systems.

There are a few choices for mobile app development, which include Swift (for iOS) and Kotlin (for Android). Swift was developed by Apple, and it is known for its speed and tight integration with Apple’s ecosystem, while Kotlin has become the go-to language for Android development. For those aiming to develop apps that are compatible with both iOS and Android, Flutter and React Native are often used. React Native is a good choice for people who are already familiar with React, as it enables the application of their web development expertise to mobile app creation.

The selection of programming languages for web and mobile development may influence your database choices. For instance, if you utilize JavaScript on both the client and server sides (through Node.js), you may prefer a NoSQL database such as MongoDB, which aligns well with the object-oriented characteristics of JavaScript. Conversely, conventional SQL databases like MySQL or PostgreSQL are often used when employing backend languages such as PHP, Python, or Java, particularly in enterprise-level applications.

In the realm of data engineering and data science, programming plays a crucial role. Python is very popular in this domain due to its extensive libraries designed for managing large datasets, constructing machine learning models, and executing deep learning tasks. For data engineering, tools such as Apache Airflow and Spark are essential. Additionally, SQL remains vital in this area, enabling data engineers to manipulate and extract data from relational databases.

When discussing automation, programming presents remarkable opportunities. If your goal is to automate complex repetitive tasks or control embedded systems, such as the software in vehicles or microwaves, programming languages like Python, C++, and Go are the leading choices. Python, with its user-friendly syntax, is frequently preferred for automating routine tasks. Meanwhile, C++ and C# are popular among game developers due to their superior performance and control over system resources, which are critical for developing complex, resource-demanding games.

A commonly overlooked aspect of learning programming is the comprehension of design patterns. These patterns represent established solutions to frequent challenges in software design. As you advance in your programming career, you will discover that these patterns facilitate the creation of better, more maintainable code. Equally significant are data structures and algorithms. Regardless of whether you are self-taught or possess a formal computer science education, a strong understanding of these core concepts will enhance your problem-solving capabilities in coding.

Programming encompasses more than merely writing lines of code; it involves grasping the underlying logic and the interconnectivity of various components. Personally, my code has evolved as a hobby over the years. With each project, my understanding of the programming pattern has deepened.

In essence, there is no definitive “best” programming language. The choice largely hinges on the specific objectives you aim to achieve, the challenges you wish to address, and your inclinations. Given the multitude of programming languages and resources accessible online, it is easy to feel inundated. But, for what it’s worth, it’s important to avoid getting stuck in the tutorial loop and start building something. What matters most is getting started, experimenting, and finding the right tools that work for you. If you are still reading, you are a legend.
