jit

Run a function with some amount of jitter (after a random amount of time). It's a real thing, I swear!

Usage

You can set timeouts:

var jit = require('jit');
 
var start = Date.now();
 
function elapsed () {
  console.log(Date.now() - start);
}
 
jit(elapsed, 100, 500); // 237
jit(elapsed, 500);      // 458
jit(elapsed, 500, 500); // 501

Or you can set jitter-y intervals:

var start = Date.now();
 
function elapsed () {
  console.log(Date.now() - start);
}
 
// clear our interval function after 500ms
var clear = jit.interval(elapsed, 100);
setTimeout(clear, 500);

jit(fn, min, [max])

Runs fn within the specified bounds. If no third parameter is specified, attempts to run the function within 0.7 * the input.

jit.interval(fn, min, [max])

Runs fn on a randomized interval between min and max. If no max is given, then it will treat the second parameter as the max. Returns a function to clear the interval
