console.log(findUsedLodash('_.each(["a", "b"], doSomething)');

//=> ['each']

```

### Use in a build task (grunt,gulp)...

```js

var findUsedLodash = require('find-used-lodash');

var fileContents = fs.readFileSync('targetFile.js', 'utf8'); //or get it from file stream

var results = findUsedLodash(fileContents);

var commaResults = results.join(',');

//then execute lodash command line with **lodash include=commaResults**

```
