====================

This library is an extension for Underscore which allows wrapping a conditional method before executing the main one, if true it calls the subsequent method.

## Features

* Prevent functions to be called unintentionally.

## Dependencies

* underscore.js (>= 1.5.0)

## Node

```javascript

var _ = require('underscore');

_.mixin(require('underscore.prefilter'));

```

## Examples

```javascript

var bark = function(sentence) {

  console.log("woof " + sentence + "!");

};

bark = _.prefilter(bark, function(sentence) {

  return !_.isNumber(sentence);

});

bark("woof"); // woof woof!

bark(123); // undefined

```
