JavaScript Objects
This question tests your knowledge of JavaScript objects and methods.
- How to write a constructor
- How to implement a method
- How to instantiate an object
- How to use a method
Hopefully you will realise that this approach to storing and accessing data is an improvement on the data structure presented in Q9.
Q10.
You are required to model a mountain with an object. You will need to write
a constructor, which takes two explicit arguments. Mountain will
require two properties, name and height.
Write JavaScript for the constructor, instantiate a Mountain
object and initialize the properties of this object, which represents Mount
Everest (see output below for values).
Now implement a method toString(), which gets the values of the
name and height properties of a Mountain
object and outputs them in an alert box. Test this method on the object you
created.
