80% often is more than enough. The remaining 20% can be researched or compensated for by an IDE if need be.
There's no need for example to know the complete JavaScript API by heart. That's what documentation and autocompletion are for. You just need to know where to look and have an understanding of how things work on a conceptual level.
- tracker1 8y agoI'd say even 50% with some firm conceptual understandings, and syntax for what you're working in/with. I don't consider myself an expert in React, but I'm more than sufficient with a relatively good understanding of concepts. Rarely do you really have to dig deep into event models, but when you do it helps to know conceptually. Beyond that, it's similar for the very back. When to lean towards a given database type or environment is helpful. It depends a lot on your needs and other specifics to a situation. I would say that a lot of higher level concepts and specific language syntax can help. I reach for map/reduce/forEach daily, as well as a ton of other things. Just knowing what's in the box can help a lot in a language... a given framework, meh, know enough to get things done and refactor/read a lot.
