#### Arguments
1. `func` *(Function)*: The function to partially apply arguments to.
2. `[arg1, arg2, ...]` *(Mixed)*: Arguments to be partially applied.
#### Returns
*(Function)*: Returns the new partially applied function.
#### Example
```js

});
var options = {
'variable': 'data',
'imports': { 'jq': $ }
};
_.defaultsDeep(options, _.templateSettings);
