A senior frontend developer writes an open letter to their younger self, offering hard-won advice for newcomers. The core message is to resist the endless chase of new frameworks and instead build a deep foundation in core web technologies. This perspective comes from years of navigating the industry's rapid changes.

The author stresses that fundamentals like HTML, CSS, and JavaScript remain constant, serving as the bedrock for any project. They recommend practical learning methods, such as using MDN Web Docs and explaining concepts aloud. Building a portfolio through side projects is also highlighted as crucial for demonstrating real-world skills and creativity.

Networking, both online and at meetups, is presented as essential for support and opportunity, especially for introverts. The letter also advises treating AI as a tool to augment skills, not replace them. Finally, it warns against the physical toll of desk work, urging developers to prioritize health and maintain a life outside of code.
