The old style of merging all of a function's variable declarations into
a single statement made some sense back in the days of var, but there's
no reason to keep doing it now that we use const and let.
- Will replace rake core_specs.
- Remove obsolete dependencies & files -- most of these were for build tasks we
are no longer using. Notably, rspec and spec_helper were deleted.
Jasmine spies now have a 'and' property which allows the user to
change the spy's execution strategy-- such as '.and.callReturn(4)'
and a 'calls' property which allows inspection of the calls a spy
has received.
* This is a breaking change *
There is a CallTracker that keeps track of all calls and arguments
and a SpyStrategy which determines what the spy should do when it
is called.
