Fastest Way to Learn ANY Programming Language: 80–20 rule

Learning a new programming language can be a daunting task. When I first started with Java, it took me months of online tutorials to grasp the basics. However, my approach changed dramatically when I joined Amazon and later Google, where I quickly adapted to Python and C++. Here, I share the method that enabled me to master multiple languages efficiently.

The Turning Point:

The pivotal moment in my learning journey came when I realized the importance of a strategic approach. Unlike my prolonged struggle with Java, I was able to deliver a Python project at Amazon within two weeks despite having no prior experience with the language. This swift adaptation continued at Google with C++, and later with JavaScript, Go, and Dart.

The Secret to Rapid Learning:

The key to my success lies in a strategy rooted in history. Post World War II, the British developed Basic English, a simplified version of the language with only 850 words, to facilitate easier learning for non-native speakers. This initiative, broadcasted through BBC’s ‘English By Radio’, proved incredibly successful. The underlying principle? The Pareto Principle, which states that 80% of outcomes come from 20% of efforts.

Applying the Pareto Principle to Programming:

This principle is not just applicable to languages but also to programming. By focusing on the most used 20% of a language’s concepts and syntax, you can cover a significant portion of practical use cases. This approach varies slightly for different programming languages, so it’s important to research the key concepts specific to the language you’re learning.

The Methodology:

The best way to learn these concepts is through interactive, hands-on practice. Watching tutorials or reading books is not enough; you need to write and break code to truly understand it. Platforms like learnpython.org for Python or W3Schools for JavaScript offer great opportunities for this kind of active learning.

Overcoming Forgetting and Expanding Knowledge:

To address the natural tendency to forget and to learn the remaining 80% of a language, the method of spaced repetition and project-based learning is highly effective. Building progressively challenging projects allows for repeated exposure to core concepts while gradually introducing more advanced ones.

Conclusion:

In conclusion, the journey to mastering programming languages doesn’t require knowing every detail but understanding and applying key concepts effectively. This method, inspired by historical language teaching and modern psychological principles, can significantly accelerate your learning process. By building projects that align with your expanding knowledge, you not only solidify your skills but also create a portfolio to showcase your capabilities. Remember, the goal is not to learn everything, but to learn the most useful aspects efficiently and enjoyably. For those eager to start this journey, I’ve compiled a list of five beginner-friendly projects to help you begin — a blend of practical experience and theoretical knowledge that will serve you well in your programming endeavors.
