The lastIndex property specifies the index at which to start the next match.
Note: This property only works if the "g" modifier is set.
This property returns an integer that specifies the character position immediately after the last match found by exec( ) or test( ) methods.
Note: exec( ) and test( ) reset lastIndex to 0 if they do not get a match.
The lastIndex property is supported in all major browsers.
Do a global search for "ain" in a string, and output the index after a match is found:
