javascript function vs. ( function() { … } ());
I'm seeing this pattern in several of TodoMVC's JS source:
(function() {
// ...
// ...
}());
What's the specific meaning of this pattern? Note that it is not the self-invoking function which is (function() {})();

You're incorrect, it is an Immediately Invoked Function Expression (IIFE). The parenthesis are just in a different place, but they bind the exact same way.
People often do it in the way you've described to get it to validate JSLint.
It's used for scoping, as JavaScript only has function and global scope (ignoring let).
