console.time & console.timeEnd
The console.time
and console.timeEnd
methods allow developers to time any routine and get a duration in milliseconds. Since JavaScript performance is becoming increasingly important, it's good to know basic techniques for benchmarking routines. One of the most basic benchmarking tools is console.time
with console.timeEnd
.
console.time
starts the time and console.timeEnd
stops the timer and spits out the duration:
// Kick off the timer
console.time('testForEach');
// (Do some testing of a forEach, for example)
// End the timer, get the elapsed time
console.timeEnd('testForEach');
// 4522.303ms (or whatever time elapsed)
Passing a timer name as the first argument allows you to manage concurrent timers. The console.timeEnd
call immediately spits out the elapsed time in milliseconds.
There are more advanced techniques for performance testing and benchmarking but console.time
/timeEnd
provide a quick manual method for speed testing!

MooTools has always gotten a bit of grief for not inherently using and standardizing namespaced-based JavaScript classes like the Dojo Toolkit does. Many developers create their classes as globals which is generally frowned up. I mostly disagree with that stance, but each to their own. In any event...
