Life after JavaScript: The Benefits of Learning a 2nd Language

This article explores the benefits of learning a second programming language after mastering JavaScript, focusing on broadening perspectives and enhancing skills. A survey reveals that a significant portion of developers are already proficient in multiple languages.

The author's personal experience with learning Scala highlights how adopting a new language, particularly one with contrasting paradigms like functional programming (FP), deepens understanding of core programming concepts. JavaScript's flexibility, while beneficial, can sometimes mask underlying issues. A different language forces a more structured approach, revealing both strengths and weaknesses of various programming styles.

The article emphasizes the advantages for self-taught developers, who may lack the formal exposure to diverse programming paradigms that computer science graduates receive. It also points out that many popular JavaScript libraries and patterns (e.g., Redux, inspired by Elm and Haskell) draw heavily from other languages. Learning these source languages provides a deeper comprehension of the underlying principles.

Furthermore, learning another language can reshape your perception of your primary language (JavaScript). By encountering alternative approaches, you critically examine your existing coding habits and underlying design choices. This is illustrated by comparing JavaScript's prototypal inheritance with languages supporting classical inheritance.

The rise of WebAssembly (WASM) is mentioned as a potential game-changer. Languages like C compiling to WASM could challenge JavaScript's dominance in the browser, though JavaScript's continued relevance is acknowledged. Learning another language safeguards against becoming overly specialized.

As a less time-intensive alternative, the article suggests exploring TypeScript, a JavaScript superset adding static typing and other features. This offers a gentler introduction to different programming paradigms without requiring a complete language shift.

The article concludes by posing questions to the reader, encouraging discussion on the benefits of multilingual programming and the impact of WebAssembly.
