When should there be a dot in JSDoc generics?

I see some people write JSDoc for JavaScript generics like this (with a dot):

/** @param {Array.<Bar>} bars the bars that should be fooed*/
function foo(bars) {}

and others like this (without the dot):

/** @param {Array<Bar>} bars the bars that should be fooed*/
function foo(bars) {}

Whats the point of the dot? Which version is correct? When should I use one and when shouldn't I?
