The author learned to code in Python, JavaScript, and C++ in a few weeks each by focusing on the most essential concepts, following a principle similar to Pareto's 80/20 rule. They emphasized interactive learning, applied spaced repetition to retain knowledge, and recommended building projects of increasing complexity to solidify their understanding. The key is to focus on the core 20% of concepts and gradually expand one's knowledge. The author also suggests that you don't need to learn everything, as long as you can effectively apply what you've learned.
