Not able to understand objects clearly


have you created a function called list i.e list();

In this instance, the keys are bill, steve and donna. Since they are are highest level keys, I call them primary keys. this is the statement quoted by mtf but i don't understand the keys should be firstName,lastName,number

I am not able to understand objects clearly,which are the other resources which could help

Contact List: 6. List them all
