javascript - String is not a function on window location href

Consider:

$('.b').click(function(){
    var link = 'www.yahoo.com';
    window.location.href(link);
});

I expect it to open www.yahoo.com, but it says "string is not a function". Why?

Try-

window.location.href = link;

or

window.location.assign(link);
