## Description
|
||
|
<section id='description'>
|
||
|
Fill in the object constructor with the following methods below:
|
||
|
<blockquote>getFirstName()
|
||
|
getLastName()
|
||
|
getFullName()
|
||
|
setFirstName(first)
|
||
|
setLastName(last)
|
||
|
setFullName(firstAndLast)</blockquote>
|
||
|
Run the tests to see the expected output for each method.
|
||
|
The methods that take an argument must accept only one argument and it has to be a string.
|
||
|
These methods must be the only available means of interacting with the object.
|
||
