Whats the difference between my code and the video?

JavaScript

I’m so confused, how could anyone be expected to get from the example to the answer?

I also changed the three to four… no go!

function caseInSwitch(val) {
  var answer = "";
  // Only change code below this line
  switch (val) {
   case 1:
      answer = "alpha";
      break;
   case 2:
      answer = "beta";
      break;
   case 3:
      answer = "gamma";
     break;
   case 3:
      answer = "delta";
     break;
}


  // Only change code above this line
  return answer;
  
caseInSwitch(1);

The 4 you have a 3 on the last case
You are missing an extra }

3

i changed the 4.

the extra } didnt help me

4 
function caseInSwitch(val) {
  var answer = "";
  // Only change code below this line
  switch (val) {
   case 1:
      answer = "alpha";
      break;
   case 2:
      answer = "beta";
      break;
   case 3:
      answer = "gamma";
     break;
   case 4:
      answer = "delta";
     break;
     }
}

What do the failing tests say?

SyntaxError: unknown: ‘return’ outside of function (22:2)

21 | // Only change code above this line

22 | return answer;

24 | caseInSwitch(1);

// running tests

caseInSwitch(1)

should have a value of “alpha”

caseInSwitch(2)

should have a value of “beta”

caseInSwitch(3)

should have a value of “gamma”

caseInSwitch(4)

should have a value of “delta” // tests comp

This is telling you exactly where the problem is. Your return statement (which I don’t see in your most recent code) is outside of your function.

9 
function caseInSwitch(val) {

  var answer = "";

  // Only change code below this line

function caseInSwitch(val) {

  var answer = "";

  // Only change code below this line

  switch (val) {

   case 1:

      answer = "alpha";

      break;

   case 2:

      answer = "beta";

      break;

   case 3:

      answer = "gamma";

     break;

   case 4:

      answer = "delta";

     break;

     }

}

  // Only change code above this line

  return answer;

}

caseInSwitch(1);
10

it says only change code above it.

11

I reset all the code and copy/pasted my answer back in and got this.

SyntaxError: unknown: Unexpected token (32:0)

31 | caseInSwitch(1);

| ^

And one of the changes you made was to add an extra }. That ended the function before your return statement.

13

I took it out.
… and I appreciate your help lol

function caseInSwitch(val) {
  var answer = "";
  // Only change code below this line
  switch (val) {
   case 1:
      answer = "alpha";
      break;
   case 2:
      answer = "beta";
      break;
   case 3:
      answer = "gamma";
     break;
   case 4:
      answer = "delta";
     break;
     
}

  // Only change code above this line
  return answer;
}

caseInSwitch(1);`

type or paste code here

function caseInSwitch(val) {
  var answer = "";
  // Only change code below this line
  switch (val) {
   case 1:
      answer = "alpha";
      break;
   case 2:
      answer = "beta";
      break;
   case 3:
      answer = "gamma";
     break;
   case 4:
      answer = "delta";
     break;
     
}

  // Only change code above this line
  return answer;
}

caseInSwitch(1);`

I got it! i have no idea what changed i just copied and pasted again and it passed. ??? Javascript sucks!!

You probably had a stray keystroke that occurred when you were making changes last time. I huge amount of errors are caused by typos.

Congratulations of figuring it out. Happy coding!
