title: Nested javascript invocation
body: <p>So recently, i often to come across instagram post that invokes javascript i.e. like this --> <strong>foo.bar().baz().qux();</strong>. The insertion of parameters can be done on so many levels. However from what i have just learned, in nested object literal, we can only do <strong>foo.bar.baz.qux();</strong> or only <strong>one</strong> parameter insertion. Can anyone show how to create nested object literals that can be invoked like this --> <strong>foo.bar().baz().qux();</strong> ?
  ^cheers,</p>
