Function assert

lib/debug/assert.js:25–35

* Verify that a certain condition is met, or throw an error if otherwise. * * This is useful for communicating expectations in the code to other human * readers as well as catching bugs that accidentally violate these expectations. * * ```js * const { assert } = require('ember-cli/lib/debug');

(description, condition)

 * If falsy, an error will be thrown.
