looper

Loop with callbacks but don't RangeError

Synopsis

Normally, if mightBeAsync calls it's cb immediately this would RangeError:

var l = 100000
;(function next () {
  if(--l) mightBeAsync(next)
})

looper detects that case, and falls back to a while loop,

var loop = require('looper')

var l = 100000
loop(function () {
  var next = this
  if(--l) probablySync(next)
})()

when you want to stop looping, don't call next. looper checks if each callback is sync or not, so you can even mix sync and async calls!
