Autoloop: perf-comparison

Goal: Benchmark every tsb function vs pandas equivalent.

Current Best Metric: 756 benchmarked function pairs

Program Issue: #221


Latest Iteration (418)

Added firstValidIndex / lastValidIndex benchmarks:

  • TypeScript: benchmarks/tsb/bench_first_last_valid_index.ts — 100k-row Series with NaN at start, end, and scattered; 500 measured iterations
  • Python: benchmarks/pandas/bench_first_last_valid_index.py — matching dataset and loop structure using Series.first_valid_index() / Series.last_valid_index()

Metric: 755 → 756 (+1)
