# Performance Comparison: tsb (TypeScript) vs pandas (Python)

## Goal

Systematically benchmark every tsb function against its pandas equivalent, one function per iteration. Each iteration picks a function that has not yet been benchmarked, writes a matching performance test for both tsb (TypeScript/Bun) and pandas (Python), runs both, and records the timing results. The benchmark results are displayed on the playground pages doc site.

This is an open-ended program — it runs continuously, always adding the next benchmark comparison.

## Target

Only modify these files:
- `benchmarks/**` — benchmark scripts and results
- `playground/benchmarks.html` — performance comparison playground page
- `playground/index.html` — add/update link to benchmarks page

## Evaluation

The metric is `benchmarked_functions`. **Higher is better.**

Start with .autoloop/programs/perf-comparison/program.md, then inspect benchmarks/** and the referenced playground/benchmarks.html and playground/index.html. The program compares one unbenchmarked tsb function with pandas per iteration; completion for an iteration means adding both benchmark scripts and recording the result on the playground page, with no finite overall endpoint.
