nanoassert
Nanoscale assertion module
Usage
var assert = require('nanoassert')
assert(a !== b, `${a} !== ${b}`)
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.
