Node : Run Method Against Array of Objects Async

Question

I have an array of homogeneous objects. I want to be able to run a a method of each of the objects in parallel. If I were to do this synchronously, it would look like:

var objs = [{run:function(){}},{run:function(){}},{run:function(){}}];

for (obj in objs) {
    obj.run();
}

I have thought about using async library, but don't see anything in there at jumps out at me that would work.

If the functions aren't async, they'd still run synchronously as there's only one thread in Node JS apps. — WiredPrairie

You can map your objects to functions first, and then call these functions in parallel using async.parallel

var async = require('async')

var objs = [{run:function(){}},{run:function(){}},{run:function(){}}];
var func2call = objs.map(function(x){return x.run})
async.parallel(func2call);
