nanoassert
Nanoscale assertion module
Usage
var assert = API
assert(declaration, [message])
Assert that declaration is truthy otherwise throw AssertionError with
optional message. In Javascript runtimes that use v8, you will get a nicer
stack trace with this error.
If you want friendlier messages you can use template strings to show the
assertion made like in the example above.
Why
I like to write public facing code very defensively, but have reservations about
the size incurred by the assert module. I only use the top-level assert
method anyway.
