How do I learn to optimize my code better?
(lemmy.ml)
I'm trying to make minesweeper using rust and bevy, but it feels that my code is bloated (a lot of for loops, segments that seem to be repeating themselves, etc.)
When I look at other people's code, they are using functions that I don't really understand (map, zip, etc.) that seem to make their code faster and cleaner.
I know that I should look up the functions that I don't understand, but I was wondering where you would learn stuff like that in the first place. I want to learn how to find functions that would be useful for optimizing my code.
I was thinking about caches and evaluating what calculations I want to do.
I fixed a project for someone simulating a machine. That took them almost 9 minutes. Simply replacing the part where they initialised a solver and used it to find a zeropoint of a quadratic function with a call to that initialiser got it down to a minute.
You should have seen their faces when we put the quadratic formula in and it took 28 seconds.
