Where do you draw the line?
When do you learn about the JVM in a Java environment? At what point should you dig into be Ruby source code?
At some point you have to treat the abstraction below you as a black box.
I've personally found it helpful to accept the black box and only dig in after I've gained more experience or at the point I feel like a lack of understanding is getting in my way.
- antris 6y ago> Where do you draw the line? When the abstraction can be considered 100% leak-proof in practical terms. Also, if you have alternative tools when you encounter a case where "X" doesn't fit, you do not need to learn about "X" as long as you have "Y". But when a solution is presented as "this must always be used", the solution should have been around for a long time with a track record of never breaking. If that's where the abstraction is, it's usually solid enough to not go any deeper. In my experience, most developers don't talk about "magic" as if it's the same thing as "abstraction". "Magic" usually means an abstraction that leaks under non-trivial conditions.
