Function

assert (desc, test) public

Module: @ember/application

Defined in packages/ember-debug/lib/index.js:69

Available since v1.0.0

import { assert } from '@ember/debug';

desc: String; A description of the assertion. This will become the text of the Error thrown if the assertion fails.
test: Boolean; Must be truthy for the assertion to pass. If falsy, an exception will be thrown.

Define an assertion that will throw an exception if the condition is not met.

In a production build, this method is defined as an empty function (NOP). Uses of this method in Ember itself are stripped from the ember.prod.js build.

        
              import { assert } from '@ember/debug';

// Test for truthiness
assert('Must pass a valid object', obj);

// Fail unconditionally
assert('This code path should never be run');
