JavaScript Class Extension Lab: `super`

Learning Goals

In this lab we're going to practice the two most common usages of the super keyword.

Define a Tree class that will act as our parent.
- A Tree instance should take in one parameter when created, species, and assign this to a property named species.
- A Tree should have a static method, definition(), that returns a short definition of all trees.
A tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves.
Define a Deciduous class that extends Tree
- A Deciduous instance takes two parameters, species and name. Use super() in the constructor to use the parent class constructor to assign species. After super(), assign the name parameter to the a name property in the Deciduous constructor
- Create a static method, definition(), that uses super to access definition() from Tree and add the following to the provide a specific definition for Deciduous:
Deciduous trees shed their leaves annually.
Define a Evergreen class that extends Tree
- An Evergreen instance takes two parameters, species and name. Use super() in the constructor to use the parent class constructor to assign species, then assign name to a property in the Evergreen constructor
- Create a static method, definition(), that uses super to access definition() from Tree and add the following to the provide a specific definition for Evergreen:
Evergreens keep their leaves all year round.
