## What it is
Benchmark.js is a JavaScript benchmarking library that supports high-resolution timers and returns statistically significant results. It powers jsPerf.com and works in both browsers and Node.js.

## Use cases
- benchmark javascript functions
- compare performance of code snippets
- measure operations per second in node
- run microbenchmarks in the browser
- find the fastest implementation among alternatives
- build a jsperf-style performance test

## When to choose
- you need statistically rigorous JavaScript benchmarks with high-resolution timers
- you want to compare multiple implementations in browser or Node.js
- you want the library behind jsPerf

## When to avoid
- you need actively developed tooling with modern runtime support
- you are benchmarking non-JavaScript code
- you need CI-integrated performance regression tracking rather than ad-hoc benchmarks

## Facets
- artifact type: library
- maturity: maintenance
- function: benchmarking
- domain: developer-tools, performance, testing
- platform: browser, cross-platform
- tags: javascript, microbenchmarking, jsperf, statistically-significant-results, high-resolution-timers, nodejs
