Frequently Asked Questions
How does the benchmark builder work?
It executes your code snippets in loops for a set duration, measuring operations per second using high-resolution `performance.now()` metrics.
Is it safe to run snippets here?
Yes. The code runs entirely locally inside your browser's context.
