Naming Pets - ;TLDR

So far, our Pet constructor just gives us an empty object. It's a start, but it's only halfway to our first feature - a pet with a name.

In this challenge, we are going to adapt the Pet function so that our pets can have names.

How would we want this to look? So far we can create a new instance of Pet by typing const pet = new Pet('Fido'); in the Node REPL.

How would you adapt that code to be able to give the pet a name? What would you expect the outcome of that action to be?

Try the following in the Node REPL:

const pet = new Pet('Fido');
 
pet.name;

What value do you get back?

Learning objectives

• setting properties of objects using constructors

• this

To complete this challenge, you will need to:

• discuss this outcome with your cohort mates:

  • what would you want the outcome to be?

  • how does this differ from what you are seeing?

  • can you suggest a way of solving the problem?

• translate this error into a new unit test - what do you expect to happen when you call new Pet('fido');?

• update your Pet constructor function to make the test pass

Once you are done, commit your work, and push to GitHub
