Want to get involved with ESLint? Here's a good first issue: https://github.com/eslint/eslint/issues/19848

Nice, it's ~3.8x faster on Node.js main branch! (I edited the linting command in Makefile after pulling in the PR)

Linting our biggest codebase with a bunch of rules (including many custom ones) currently takes about 38s. Adding `--concurrency=auto` dropped it to 12 seconds. Can't wait for this to be released.
