> Master the fundamentals because those never change Do that for sure if you're doing web app development. The core fundamentals have not changed much in 20 years. Its HTML, CSS, JS and an HTTP server and likely a database. All the frameworks, packaging of client side code, code transpilers, etc. have to do the core stuff and once you understand what/how they do their thing it should be relatively easy to pick up another "new" tech that does these same things. Get good at maintaining, refactoring and extending existing applications. Understand the business value of doing these things vs. a common crutch engineers go to of "that code is crap, we have to rewrite". Being helpful and flexible with solutions to business problems is going to be better than an engineer that wants to rewrite everything, has an ego about their code, says no a lot, etc.
