/*1 Write a function called billTotal that can be used to calculate the total to be paid at a restaurant -- 
including tip and tax -- given the subtotal (i.e. cost of food and drinks). 
We can assume that the tip will be 15% and tax will be 9.5%. Make sure that the tip does not include the tax!*?

/*2 Complete the below function called range that takes two integers as parameters, 
start and end, and returns an array containing all the whole numbers between them starting 
with start and up to end (you can use a any loop. The function definition should look like this:

function range(start, end) {
  // YOUR CODE HERE
}
You should be able to use it like so:

range(0, 4); // => [0, 1, 2, 3]
range(2, 7); // => [2, 3, 4, 5, 6]
range(10, 10); // => []
range(10, 2); // => []
After you write your function, you can test it using the above inputs to make sure that it behaves correctly.

/*3 Write a function called 'getFullName' that takes in an object which has this structure:

var person = {
   name : {
      first : "Alyssa",
      middle: "P.",
      last: "Hacker"
   },
   age : 26
}
 and returns the person's full name.

 `getFullName(person); //"Alyssa P. Hacker"`
Note: some person objects passed in may be missing a middle name. In such cases, 
the function should return the first and last name separated by 1 space.

Example:

var personB = {
   name: {
      first: "Ben", 
      last: "Bitdiddle"
   }, 
   age: 34
}

getFullName(person); //"Ben Bitdiddle"*/

      middle: "P.",

var personB = {
   name: {
      first: "Ben", 
      last: "Bitdiddle"
   }, 
   age: 34
}
console.log("Problem 3: ",getFullName(person));
console.log("Problem 3: ",getFullName(personB));

function getFullName(obj){
    return Object.values(obj.name).join(' ');

, returns the person (that is, your function should return an object) with the longest name (first, middle & last).
