Is there any way to retrieve a Web by title using SharePoint 2013 JSOM without using the enumerator?

I need to get a subweb with a particular title using JSOM. So far, the only way I can see to do this would be to use code similar to the following:

function getStuff() {
    var oWebsite = clientContext.get_web();
    collWebs = oWebsite.get_webs();
    clientContext.load(collWebs, 'Include(Title, Url)');

    clientContext.executeQueryAsync(
        Function.createDelegate(this, this.onQuerySucceeded), 
        Function.createDelegate(this, this.onQueryFailed)
    );
}

function onQuerySucceeded() {
    var webInfo = '';
    var websEnumerator = collWebs.getEnumerator();

    while (websEnumerator.moveNext()) {
        var oWeb = websEnumerator.get_current();
        webInfo += 'Title: ' + oWeb.get_title() + ' Url: ' + 
            oWeb.get_url() + '\n';
    }
}

where I'm forced to go through the entire collection of webs using the enumerator. Is there any way to get a particular web, similar to the way you can do the following on a List Collection?

get_lists().getByTitle("MyCustomList");
