replacing a varying substring with itself plus

[kurt]

Hi,
I'd like to globally replace a substring specified by a regular
expression with itself along with some additional characters.
example:

var oldString = 'asdf BRACKETTHISasdfsdf sd asdBRACKETTHISasdf asd';

var newString =
oldString.replace(/\s\w*BRACKETTHIS\w*/g, '<' + ?some expression that
accesses current match? + '>' )

And newString winds up as:
'asdf <BRACKETTHISasdfsdf> sd <asdBRACKETTHISasdf>
asd'

Is there a way to do this, or do I have to use other methods?

Thanks for helps,
Kurt

Add parentheses around the substring you care about and use $1 in the
replacement text.
.replace(/\s\w*(BRACKETTHIS)\w*/g, '<$1>' )
