Executes a search for a match in a specified string.

The exec method syntax has these parts:

Part Description
rgexp Required. A Regular Expression object. Can be a variable name or a literal.
str Required. The string to perform a search on.
The results of an exec method search are placed into an array.

If the exec method does not find a match, it returns null. If it finds one or more matches, the exec method returns an array, and the RegExp object is updated to reflect the results of the search.
