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?

Answer 1

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.

Answer 2

Use toString();
(new Date()).getTime()+""; instead (new Date()).getTime().toString();
