Inheritance and Method Overloading in cc.Class

Greetings! Let’s say I have ChildB that extends ParentA–both of these classes are of type cc.Class.

Is there a way for ChildB to call ParentA’s update method and then run its own update code?

Example:

In ChildB.js:

update(dt)
{
// Call ParentA’s update method
// Do more stuff
},

…or is it possible to use ES6 and create a class that extends a cc.Class/cc.Component?

to call parent function:

this._super(dt);
