Exactly. Some of the best folks I&#x27;ve hired or worked with had no experience with the framework&#x2F;language we ended up using. Knowing fundamentals is far more important.<p>This is also why managers that pick languages based on &quot;hireability&quot; are wrong for the most part. In any non trivial system, learning the domain and existing codebase will dominate the time to learn a new language. It&#x27;s a nice bonus to have experience with a certain piece of tech, and for baby apps that might be the most important thing. But not for real systems.
