⚡ Bolt: [performance improvement]#254
Conversation
Replaces a severe O(N*M) algorithmic bottleneck in `diffTests` where two arrays were cross-compared using nested `.filter()` and `.some()` loops. Even though RegExps were pre-compiled, the array iteration itself triggered redundant evaluations. This converts the logic to a single pass that populates two `Set` objects, enabling O(1) membership checks to extract `onlyInCode`, `onlyInDocs`, and `matched` arrays.

💡 What: Replaced nested
.filter()and.some()cross-comparisons between two arrays with a single nested loop that populates twoSetobjects for O(1) membership lookups.🎯 Why: To fix an O(N*M) algorithmic bottleneck. Even though the regular expressions were already pre-compiled (avoiding RegExp instantiation overhead), iterating through the arrays repeatedly via
array.filter(a => !otherArray.some(b => match(a, b)))caused redundant iterations and checks across the entire array for every single element.📊 Impact: Reduces array iteration and matching attempts from$3 \times N \times M$ down to a single $N \times M$ pass. Tests run much faster when matching large project directories.
🔬 Measurement: Run the test suite (
node --test tests/*.test.mjs) to verify correctness, and test against a large test directory to observe the reduced CPU overhead.PR created automatically by Jules for task 3732714359725914287 started by @raccioly
