/**
 * @param {A}�a
 */
const foo = (a) => {
};

command

timeout -v 100 oxlint -D all -D nursery --import-plugin --jsdoc-plugin --jest-plugin --vitest-plugin --jsx-a11y-plugin --nextjs-plugin --react-perf-plugin TEST___FILE.ts --fix

rustup component add llvm-tools-preview --toolchain nightly-x86_64-unknown-linux-gnu

export RUST_BACKTRACE=1
export ASAN_SYMBOLIZER_PATH=$(which llvm-symbolizer-18)
export ASAN_OPTIONS=symbolize=1
RUSTFLAGS="-Zsanitizer=address" cargo +nightly build --target x86_64-unknown-linux-gnu
