These days I'll just dump all relevant code into an LLM and have it explained to me instantly.

Being able to ask questions about the parts that are unclear (or just plain wrong) is so much easier than trying to cram the entire thing into my brain RAM.

In my experience it actually helps me learn faster too, since I rarely get stumped on random gotcha's anymore.

Nah, i use debuggers all the time despite also using LLM agent all the time. They are great, but limited and often just go into a perpetual loop of not being able to debug something. I toss in some breakpoints and figure out exactly what is going on.
