Ember.assert()

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.

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

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