True proficiency in programming is a multifaceted concept, encompassing various skills and attributes. It may involve the ability to rapidly develop production-grade code, a deep understanding of sought-after frameworks, or mastery of the fundamentals of programming languages. While an all-rounded programmer may possess a combination of these traits, the journey toward becoming a 'better' programmer often prompts the question of where to focus. Despite the allure of popular frameworks, I contend that achieving true adeptness requires prioritizing the mastery of fundamental programming languages.

Exploring widely used frameworks is a common pursuit in the quest for proficiency. These frameworks offer expedited development by providing built-in functions and solutions, enabling rapid deployment of code. However, a potential pitfall lies in relying solely on frameworks, as it can lead to a superficial understanding of the underlying code. Rather than depending solely on shortcuts provided by frameworks, aspiring programmers should delve into understanding the core fundamentals of programming languages. This approach ensures a comprehensive grasp of the mechanisms driving the code, fostering a more profound and sustainable proficiency.

Taking an example from Korea's popular backend framework, Spring Boot, which utilizes Spring Data JDBC for convenient CRUD operations, emphasizes the importance of understanding underlying mechanisms. Without delving into the core concepts of Java, object-relational mapping, SQL, and repository patterns, one's knowledge might be limited to leveraging the abstractions provided by the framework. A truly proficient programmer should be capable of deciphering how these in-built solutions work independently of the framework, showcasing a deep understanding that transcends the immediate tools at hand.

Language skills are a timeless investment for programmers. Unlike frameworks, which may become obsolete over time, programming languages exhibit greater resilience. By prioritizing the mastery of programming languages, individuals equip themselves with skills that withstand the ever-changing landscape of technology. While frameworks are valuable allies, they should complement, not substitute, fundamental knowledge of computer science. This approach empowers programmers to think critically and adapt their skills to tackle diverse challenges, ensuring long-term proficiency in the dynamic field of programming.
