regex object

[jigneshjsoni]

<script type="text/javascript">
 
var str="Hello world!";
 //look for "Hello"
 var patt=/Hello/g;
 var result=patt.test(str);
 document.write("Returned value: " + result);  
</script>

when var patt is cretaed as shown above, how does it create an object of RegExp type ? To create an object of a particular type, its required to be created as "var patt=new RegExp(pattern,modifiers);" If we just specify "var patt=/Hello/g;" how will script understand that its of RegExp type only and nothing else ?

Thanks

It is the literal syntax of the regex object, just as we have string literal, number literal, object literal and such.
