Simple stopwatch for execution time measurement.

$ npm install exec-stopwatch

var Stopwatch = require('exec-stopwatch');

var stopwatch = new Stopwatch();

stopwatch.start();

syncFunction();
stopwatch.lap();

syncFunction();
stopwatch.lap();

syncFunction();
stopwatch.lap();

stopwatch.stop();

console.log(stopwatch.getLapsTime());
console.log(stopwatch.getElapsedTime());

You can find examples here

You can pass options object to Stopwatch constructor with follow fields:

• formatter(time) — function for transforming time before returning from getLapsTime and getElapsedTime functions.

• .start() — runs stopwatch;
• .lap() — saves elapsed time of current lap. Returns this time in nanoseconds;
• .stop() — stops stopwatch;
• .getLapsTime() — returns times for each lap;
• .getElapsedTime() — returns time, elapsed from the moment of start method call until stop method call.
