parseFloat('2a') === 2; //true
isNaN(+'2a'); //t...

What's the difference between lists and tuples?
...er.
Using this distinction makes code more explicit and understandable.
One example would be pairs of page and line number to reference locations in a book, e.g.:
my_location = (42, 11) # page number, line number

What is code coverage and how do YOU measure it?

As to how we use it - code coverage is one of our exit criteria for each milestone. We have actually three code coverage metrics - coverage from unit tests (from the development team), scenario tests (from the test team) and combined coverage.
