# Pend

Dead-simple optimistic async helper.

## Usage

```js

var Pend = require('pend');

var pend = new Pend();

pend.max = 10; // defaults to Infinity

setTimeout(pend.hold(), 1000); // pend.wait will have to wait for this hold to finish

pend.go(function(cb) {

  console.log("this function is immediately executed");

  setTimeout(function() {

    console.log("calling cb 1");

    cb();

  }, 500);

});

pend.go(function(cb) {

  console.log("this function is also immediately executed");

  setTimeout(function() {

    console.log("calling cb 2");

    cb();

  }, 1000);

});

pend.wait(function(err) {

  console.log("this is excuted when the first 2 have returned.");

  console.log("err is a possible error in the standard callback style.");

});

```

Output:

```

this function is immediately executed

this function is also immediately executed

calling cb 1

calling cb 2

this is excuted when the first 2 have returned.

err is a possible error in the standard callback style.

```
