How do I match with Regex with word boundaries?

I am using JavaScript:

::add ::stuff more::word

I want to match ::add and ::stuff , but not ::word .

How can I do this?

You can use a non-word boundary \\B here:

var r = '::add ::stuff more::word'.match(/\B::\w+/g);
console.log(r); //=> [ '::add', '::stuff' ]
