The author shares their experience of learning ES6 with the help of Python, emphasizing the similarities and differences between the two programming languages. Key differences include the importance of whitespace in Python, which is not a factor in JavaScript, and the presence of type coercion in JavaScript but not in Python. The text explores how functions, methods, and block scopes are structured similarly in both languages, while also highlighting the introduction of template literals, default parameters, and rest parameters in ES6, which parallel features in Python. The author notes that ES6 classes provide syntactic sugar for object-oriented programming, similar to Python's built-in classes, making concepts like inheritance more accessible. Ultimately, the shared syntax and concepts between Python and ES6 facilitated the author's learning process, illustrating how understanding one language can aid in learning another.
