1. following following code snippet, try to get code hint after `bruce.` ``` var Vulnerable = { wound: function (hp) { this.health -= hp; }, kill: function () { } }; var Person = Class.create(Vulnerable, { initialize: function () { this.health = 100; } }); var bruce = new Person(); bruce. ``` ->code hints are: kill, wound, missing "initialize". 2. type initialize() after "bruce.". 3. get code hint by type bruce. again ->code hints now: initialize, wound, "kill" is removed Expect: at step 1, "initialize" should be found. at step 3, code hint should be: initialize, kill, wound
