Nanoscale assertion module
var assert = require('nanoassert')
assert(a !== b, `${a} !== ${b}`)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.
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.
Docs for the previous version, which is used by many modules on npm, can be found here
npm install nanoassert
