Make a Person

Fill in the object constructor with the following methods below:

getFirstName()
getLastName()
getFullName()
setFirstName(first)
setLastName(last)
setFullName(firstAndLast)

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.
*/
const Person = function(firstAndLast) {
  // Only change code below this line
  // Complete the method below and implement the others similarly
  const [first, last] = firstAndLast.split(' ');
  let firstName = first;
  let lastName = last;
  let fullName = firstAndLast;
  this.getFirstName = () => firstName;
  this.getLastName = () => lastName;
  this.getFullName = () => `${firstName} ${lastName}`;
  this.setFirstName = (first) => firstName = first;
  this.setLastName = (last) => lastName = last;
  this.setFullName = (firstAndLast) => {
    const [first, last] = firstAndLast.split(' ');
    fullName = firstAndLast;
    this.setFirstName(first);
    this.setLastName(last);
  }
};
