How to get multiple lists using JSOM in sharepoint?

I have issue on retrieving multiple lists. Is there a way that I can use JSOM to make multiple request in different lists? Thank you.

Old question but I'd like to post this answer for future readers.

Just get all your lists then load them one after another:

var ctx = SP.ClientContext.get_current();

// assuming you're working with the appweb
var list1 = ctx.get_web().get_lists().getByTitle("list1");
var list2 = ctx.get_web().get_lists().getByTitle("list2");
var list3 = ctx.get_web().get_lists().getByTitle("list3");

ctx.load(list1);
ctx.load(list2);
ctx.load(list3); // multiple loads required

ctx.executeQueryAsync( // one call to the server
         function(){
            // do something with the lists
         },
         function(){
            // fail
         });

Also a good idea to utilize jQuery's promise pattern when working with SharePoint's JSOM api, like so:

// extending the jQuery namespace for convenience
// if this is a bad idea performance wise or something
// I would like to hear from someone :)
$.extend({    

execQAsync: function(ctx){
   var dfd = $.Deferred();

   ctx.executeQueryAsync(
       function(sender,args){
           dfd.resolve();
       },
       function(sender, args){
           dfd.reject();
       });

    return dfd.Promise();
   }

});

Then you can go about doing things this way:

$.execQAsync(ctx)
 .done(function(){
     // do something when the promise resolves
 })
 .fail(function(){arguments[1].get_message() });

See Optimal/preferred way to call 'SP.ClientContext.executeQueryAsync' in SharePoint

P.S Doublecheck lettercasings etc, i wrote all this in a fiddle.
