# contra-find

[![build status](https://secure.travis-ci.org/smallhelm/contra-find.svg)](https://travis-ci.org/smallhelm/contra-find)

Using contra, asynchronously find a value in a collection that matches a condition.

```js

var λ = require('contra');

var find = require('contra-find');

var items = [

  [1, 2],

  [2, 3],

  [3, 4],

  [4, 5],

  [5, 6]

];

find(λ, items, function(item, next){

  console.log('item :', item);

  process.nextTick(function(){

    console.log('check:', item);

    next(undefined, item[0] === 3);

  });

}, function(err, item){

  console.log('item found!', item);

});

```

output

```

item : [ 1, 2 ]

check: [ 1, 2 ]

item : [ 2, 3 ]

check: [ 2, 3 ]

item : [ 3, 4 ]

check: [ 3, 4 ]

item found! [ 3, 4 ]

```

Notice that it iterates in series and stops as soon as the item is found.
