Speed-ups with the reasoning

Optimize mode looks for algorithmic wins, repeated work and needless allocations, then shows a cleaner version with the trade-offs explained.

Make this faster:

const common = a.filter(x => b.includes(x));

That’s O(n·m) because includes scans b each time. Use a Set for O(n + m):

const setB = new Set(b);
const common = a.filter(x => setB.has(x));

FAQ

Will optimization change what my code does?

Muse aims to keep behavior identical and calls out any edge cases. Run your tests to confirm.

Can it optimize SQL?

Yes — or use the SQL tool for query-specific advice like indexes and rewrites.

Does it profile my code?

No. Muse reasons about the code you paste. Use a profiler to confirm real-world gains.
