laters

A really simple (but useful?) utility lib for async scatter/gather (both ordered, and keyed) and pipelines.

Ripped from the guts of Anvil.

Pardon the silly examples, imagine that the async calls are doing something super important :)

Parallel - async map with preserved results

laters.parallel( [ 1, 2, 3], function( x, done ) { done( x + 1 ); }, console.log );
 
// results in [ 2, 3, 4 ]

Execute a hash of asynchronous functions and store results in keys

var hash = {
    a: function( done ) { done( 1 ); },
    b: function( done ) { done( 2 ); },
    c: function( done ) { done( 3 ); }
};
laters.mapped( hash, console.log );
 
// results in { a: 1, b: 2, c: 3 }

Pipeline - asynchronously execute a pipeline

var actions = [
    function( x, done ) { done( x + 5 ); },
    function( x, done ) { done( x / 2 ); },
    function( x, done ) { done( x * 4 ); },
];
laters.pipeline( 5, actions, console.log );
 
// results in 20 ( 5 + 5 == 10 / 2 == 5 * 4 == 20 )
