We also teach how to profile with detailed instructions.
@cammchenry just added a section on how to get CPU cache misses with Mac instruments.

@boshen_c Really excited for folks to try this one out! I would love to hear about real-world improvements from this if anyone tries it on their codebase 👀

Small file optimization: linting the vscode repo is 1.33x faster than the previous version, by @cammchenry

This optimization gets better with more rules and plugins: linting the VS Code repository on my M1 laptop with ALL plugins and 430 rules enabled is 1.45x faster and shaves off around 1 second of time. This pretty much best case scenario though: it's more typically 10-20% better.
English
It was all worth it in the end, this PR should make oxlint much speedier.

@boshen_c I don't know why this code is so much slower in only one case 😭
English
Oxlint is now up to 6% faster when linting the VS Code repository with the Jest plugin (and up to 4% faster with them disabled)
English
It also made it 26% slower for another file unfortunately, so I still need to look into why that is:
English
It's amazing how cache locality can change performance. I updated some code in oxlint to use an iterator and only iterate once, versus three times, and it made the code up to 30-38% faster:

Copilot has been great for coding with one hand. I can hold my 4 week daughter with one hand, and I can type a few letters with my other hand and it usually saves me a ton of keystrokes.

@cammchenry migrated all oxlint's regular expression rules to AST visits. Look how simple and clean this is. PR: github.com/oxc-project/ox…

Also, memory safety aside, I would use Rust just for the ecosystem and tooling: cargo, regex, doctests, docs.rs, criterion, etc.

Coming back to @rustlang after several years, and everything has improved so much. Things are faster, so many more APIs, and it feels easier to get things to compile.
