An accurate timer written in javascript

Primary LanguageJavaScript

An accurate, multienvironment timer

accurate_timer uses requestAnimationFrame() and performance.now(), defaulting to setInterval if it's used in a non-browser or older environment.

Based on my own (unscientific) measurements, the timer in a node.js environment tends to be accurate to about 3/1000ths of a second. In a browser environment it's a little less than 1/1000ths of a second.

Usage

  • Create a timer object:

     var timer = new Timer(<callback>, <interval>);

    The callback will be called every interval milliseconds.

  • start / stop the timer:

     timer.start();
 timer.stop();

All done! I hope you enjoy 😊
