Common assertion functions, especially useful for testing

A library of assertion functions. If the assertion is false an AssertionError will be thrown which will result in pretty-printed diff of the failing assertion.

This module is browser compatible, but do not rely on good formatting of values for AssertionError messages in browsers.

import { assert } from "@std/assert";

assert("I am truthy"); // Doesn't throw
assert(false); // Throws `AssertionError`
