Simple JavaScript benchmarking tool inspired by my bad understanding of how Criterion.rs works.
Let's be honest, I'm terrible at statistics. This approach that I took here is probably incorrect, but the results appear to be stable enough so I'm happy to use it for my personal projects.
Any ideas on improving the algorithm are very welcome!
npm install -g @indutny/bencher// benchmark.js
export const name = 'runner';
// Function to benchmark
export default () => {
let sum = 0;
for (let i = 0; i < 1e6; i++) {
sum += i;
}
// Make sure to return a side-effect value (possibly a result of the
// run) to ensure that the pure function calls are not optimized out by the
// JIT compiler.
return sum;
};$ bencher benchmark.js
