As someone who only learned a few things about programming, is optimizing code an easy thing? I've read about that many times but the only thing I could imagine (and I had to imagine it as I'm not really a programmer) is that perhaps their codes could be more efficient (so rewriting their code so that ten lines do the job of thirty for example) but I feel like if they lack the logic skills or math skills to do it then perhaps that's why the code contains large functions and such.
But again, I'm not a coder, so I've no idea how in practice code can be optimized.
Shorter is usually faster so your right on that account but not always. There are few things like optimizing for cache hits that can vastly speed up programs but are hard to do. Most slow programs are due to technical debt, high dependencies usage, mixed with laziness and lack of interest in developers with speeding up their program.
