npm install looperLoop with callbacks but don't RangeError
Normally, if mightBeAsync calls it's cb immediately
this would RangeError:
`` js`
var l = 100000
;(function next () {
if(--l) mightBeAsync(next)
})
looper detects that case, and falls back to a while loop,
in computer science something like this is called a trampoline)
this module is simpler than other trampoline libraries such as tail-call
because it does not preserve arguments. But this is still useful
for looping when async recursion is sometimes sync.
This is about 10 times faster than using setImmediate
` js
var looper = require('looper')
var l = 100000
var next = looper(function () {
if(--l) probablySync(next)
})
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!
