}

Allows you to time operations.

Tries to get the elapsed ms. Throws if the Stopwatch has not been started.

console.log(w.elapsed()); // 1000

Reset the stopwatch.

const w = stopwatch();

w.start();

w.stop();

w.reset();

w.elapsed(); // Error: "Call `.start()` first!"

Start the stopwatch.

const w = stopwatch();

w.start(); // start counting

Stop the stopwatch.

const w = stopwatch();

w.start();

await sleep(1000);

w.stop(); // stop counting

await sleep(1000);

console.log(w.elapsed()); // 1000
