⚡ Bolt: Optimize chained array operations in core utilities#46
Conversation
Replace multiple chained array operations (`.map().filter().map()`, `.map().filter().reduce()`) with single `for` loops in: - `packages/core/src/engines/stimulusInjector.ts` - `packages/core/src/engines/prospectiveMemory.ts` - `packages/core/src/utils/coerce.ts` - `packages/core/src/web/surveys.ts` This eliminates unnecessary intermediate array allocations, reducing memory usage and garbage collection overhead, particularly in high-frequency paths.

💡 What: Replaced several instances of chained array operations (
.map().filter().map()and.map().filter().reduce()) with singleforloops across multiple utility and engine files in the@experiments/corepackage.🎯 Why: Chained array methods allocate a new intermediate array at every step. In functions like
toNumberArray,asStringArray, andcomputeScores, which may be called frequently or operate on moderately sized arrays, this creates unnecessary memory allocations and garbage collection overhead.📊 Impact: Eliminates N intermediate array allocations for an array of size N in each operation, improving memory efficiency and reducing execution time in these specific code paths.
🔬 Measurement: Run the test suite (
npm run test --workspaces --if-present). No regressions should occur. Micro-benchmarks oftoNumberArrayor similar utility functions would show improved performance and reduced memory allocations compared to the chained version.PR created automatically by Jules for task 2913135739689122817 started by @Howchie
