tiny-each-async
Asynchronous iterator function similar to (and inspired by) async.each, with support for concurrency limit and item index.
Usage
each(array, [limit], iterator, [callback])
Arguments:
- array - An array of items to iterate through.
- [limit] - An (optional) integer for determining how many
iterator
functions should be run in parallel. - iterator(item, [index], callback) - A function to be applied to each item in the array. When it has finished processing the item then the
callback
function should be called (in case of a failure with theerror
argument, otherwise none). - callback(err) - An optional callback function that gets called when either all
iterator
functions have finished or one of them has returned an error.
Example
var eachAsync = ;var timeouts = 300 100 2000; ;

FAQ
- Why the name?
Other possible names were already taken, and the actual source code is tiny.
- Why create another async library?
Because doing your own thing is fun.
- What if my iterator function is sync, but I want it && the callback to be async?
Then you might want to use dezalgo.
