RegExp match until end of word

So I'm trying to write a JavaScript variable-highlighting regular expression, so that variable declaration names are highlighted by the following code:

var foo = 'bar',
    raz = 'zar',
    wat

So far I have a regexp that whichights foo and raz but not wat since the regexp works by ending with the = character.

(var|,)(.*?)=

How can I modify this regexp so that is also highlights wat?

I have a feeling that the missing piece is to swap the = with an ending word boundary match.

Can you try this regex:

(?:var|,)\s*(\w+)(?= *=|$)

You can try this

(var)((.*)=(.*),?)+
