stopwatch-lite

A stopwatch for all your time-measuring needs

Installing

npm install stopwatch-lite

Features

start() starts stopwatch, has no effect if the stopwatch is running

stop() stops stopwatch, has no effect if the stopwatch is stopped

reset() stops stopwatch and sets time to 0

To use multiple stopwatches, pass in the name of a particular stopwatch. Stopwatch names can be any value (including functions, objects, or any primitive).

import stopwatch from "stopwatch-lite";

stopwatch.start();

sw.start(123);

foo().then(() => {
  sw.stop("example");
  console.log(`foo execution time: ${sw.read("example")} ms`);
});

bar().then(() => {
  sw.stop(123);
  console.log(`bar execution time: ${sw.read(123)} ms`);
});

import sw from "stopwatch-lite";

let totalExecutionTime = 0;

for (let i = 0; i < 42; i++) {
  sw.start();
  foo();
  totalExecutionTime += sw.read();
  sw.reset();
}

console.log(`average execution time: ${totalExecutionTime / 42} ms`);
