html formatting in javascript

I have a variable:
words[1] = "hello sam"

Is there a way to make it respect html formatting such as..
words[1] = "<b>hello</b><br><i>sam</i>"

like this :

words[1].split(' ');
you can use "split" to split the string to an array,then ,you know

you could use document.write="<b>hello</b><br><i>sam</i>"

and put that into a function.

Thank you for the replies.

I'm very new to javascript. Can you describe "split" more.

And for document.write, where would I place this?

split is a function of "String" you can split a string with the function ...
detail usage you may find in google...so does "document write"
