Learning to code can feel like climbing a mountain, especially when you’re just starting out. With so many programming languages and learning paths available, it’s easy to get lost and overwhelmed. But what if there was a “best way” to begin your coding journey, a path that leverages decades of experience to make the process smoother and more effective?
According to a seasoned programmer with over 35 years in the field, the secret lies in embracing functional programming concepts right from the start. Diving into functional programming, even partially, can lay a robust foundation for any aspiring coder.
When it comes to choosing your first programming languages, simplicity is key. The expert recommends starting with languages known for their straightforward syntax, such as LISP (or its dialects like Scheme and Clojure) or Smalltalk (specifically Squeak).
John McCarthy, a pioneer in computer science and the creator of LISP, passed away in 2011.
Why these languages? Because their syntax is incredibly easy to grasp. LISP dialects are famous for having just one syntax rule, while Smalltalk comes in a close second with only a handful of reserved words. This simplicity is a significant advantage for beginners. In LISP, everything revolves around the structure: (function arg1 arg2 ...argN). Smalltalk, on the other hand, is built upon sending messages to objects, with a minimal set of reserved words like self, super, true, false, and nil.
Choosing languages with simple syntax at the beginning is strategic. It frees your mind to focus on understanding core programming concepts rather than wrestling with complex language rules. Unlike languages like Java or PHP, which come with a plethora of reserved words and intricate syntax, LISP and Smalltalk allow you to concentrate on the fundamental principles of programming.
Once you’ve selected a language, the best approach is to start coding actively and enthusiastically. The goal is to solidify your understanding of basic concepts such as variables, bindings, functions, and input/output operations. A practical method for learning a new language is to undertake a small project, like creating a simple game such as “Pong.” This type of project necessitates learning how to handle keyboard input, manage data, and display graphics – all essential programming skills.
However, it’s crucial to begin with small, manageable steps. Even successfully printing “2+2” and getting the correct result can be a motivating mini-victory. Gradually increase complexity by taking user input, processing files, and performing calculations.
The learning process is built upon continuous small successes. And when you encounter errors – which is inevitable – embrace them as learning opportunities. Mistakes are integral to learning. In fact, the more errors you make early on, the faster you’re likely to learn and improve.
Learning to code is a journey that lasts a lifetime. Embrace the challenges, celebrate the small wins, and enjoy the process of continuous growth.
