SP JSOM: is there any way to get the group by name instead of getById(10)

Question

is there a way I can use the below with something like getByName(thisGroup), instead of getById(10) in SP 2010 jsom:

function setSomeUsers(dataObj, projGroup) {
    var clientContext = new SP.ClientContext.get_current();
    var collGroup = clientContext.get_web().get_siteGroups();
    //instead of this:
    var oGroup = collGroup.getById(10);
    // something like the below
    // var oGroup = collGroup.getByName(projGroup);
    var userCreationInfo = new SP.UserCreationInformation();
    userCreationInfo.set_email(dataObj.userEmail);
    userCreationInfo.set_loginName(dataObj.userLogin);
    userCreationInfo.set_title(dataObj.userTitle);
    this.oUser = oGroup.get_users().add(userCreationInfo);
    clientContext.load(oUser);
    clientContext.executeQueryAsync(Function.createDelegate(this, this.onSetAdminsQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));

}

function onSetAdminsQuerySucceeded() {   
    alert(this.oUser.get_title() + " added.");
}

// plus the failed here

so if the above isn't possible, is there a way to get the name and id out of get_sitegroups() callback?

appreciated as always!

AFAIK, it's only possible to use getByName in SharePoint 2013, not in 2010. See MSDN reference for more information

 var groupCollection = clientContext.get_web().get_siteGroups();
 visitorsGroup = groupCollection.getByName("SomaGroupName");
