Details

We will now use our knowledge about else if statements and comparison with equality, less and greater operators.

In the game of golf each hole has a par for the average number of strokes needed to sink the ball. Depending on how far above or below par your strokes are, there is a different nickname.

Your function will be passed a par and strokes. Return strings according to this table (based on order of priority - top (highest) to bottom (lowest)):

Strokes	Return
1	"Hole-in-one!"
<= par - 2	"Eagle"
par - 1	"Birdie"
par	"Par"
par + 1	"Bogey"
par + 2	"Double Bogey"

= par + 3 | "Go Home!"

par and strokes will always be numeric and positive.

Remember to use Read-Search-Ask if you get stuck. Try to pair program. Write your own code.

Problem Explanation:

• Change the code below // Only change code below this line and above // Only change code above this line
• Take note that you are editing the inside of the golfScore function.
• You will have to make the function return exactly the same string as shown shown on table, depending on the value of the parameters par and strokes that are passed in to your function.

Hint: 1

• +number -number can be used to increase or decrease a parameter in your condition.

Hint: 2

• You can chain else if statements to return different values in different scenarios.

Hint: 3

• Control the flow of your function based on the tables order of priority - top (highest) to bottom (lowest) to return matching string values.

Spoiler Alert!

Solution ahead!

Code Solution:

function golfScore(par, strokes) {
  // Only change code below this line
  if (strokes === 1){
    return "Hole-in-one!";
  } else if (strokes <= par - 2){
    return "Eagle";
  } else if (strokes === par - 1) {
    return "Birdie";
  } else if (strokes === par) {
    return "Par";
  } else if (strokes === par + 1) {
    return "Bogey";
  } else if (strokes === par + 2) {
    return "Double Bogey";
  } else if (strokes >= par + 3) {
    return "Go Home!";
  }
  // Only change code above this line
}
// Change these values to test
golfScore(5, 4);

Code Explanation:

• Comparing the parameters stroke and par value to return appropriated string value.
• Using else if statement for flow control
• else will return string "Go home!" to every condition where strokes are equal to par +3 or higher
