How can I rectify " Expected String instead saw "" " using jslint?

Question

I've got a regular expression: ``` return (str+'').replace(/^(.)|\s(.)/g, function ( $1 ) { return $1.toUpperCase ( ); } ); ``` I get following jslint error: ``` Expected String instead saw "" ``` How can I rectify this error?

Accepted Answer

It wants you to use

```
String(str)
```

isntead of

```
(str+'')
```

Invoking the String function as a "cast" is a slightly cleaner way to convert something to a string from some other type.
