learning exercise 9

[Danbaba1]

Exercise:
Mixed Juices

issue:
.I am unable to use while loop and switch statement to run the code.
. Also I am unable to come up with an algorithm to solve the code.

Where:
function 2

@Danbaba1 I've seen my error with the switch statement while we were taking a look at the exercise together earlier. It was supposed to be case "small": and not case lime === "small":. I told you it must be one silly mistake I must have been making - and there it is. Also, just like I said using a while or do-while loop doesn't work here.

• Copy and paste the function below unto your exercism editor, let me know if the test passes or not. Just reply here in this issue, no need to send a mail.
• I will make a video to explain it. I will make and put the link to the video here in this issue comment tomorrow evening or night.

function limesToCut(numberOfLineWedges, supplyOfWholeLimesArray) {
  let addUpWedgesFromArray = 0;
  let numberOfLimes = 0;

  supplyOfWholeLimesArray.forEach((lime, index) => {
    let amountOfWedgesFromLime = 0;
    switch(lime) {
      case "small":
        amountOfWedgesFromLime = 6;
        break;
      case "medium":
        amountOfWedgesFromLime =  8;
        break;
      case "large":
        amountOfWedgesFromLime = 10;
        break;
    }

    if (addUpWedgesFromArray < numberOfLineWedges) {
      addUpWedgesFromArray += amountOfWedgesFromLime;
      numberOfLimes = index + 1;
    }
  });

  return numberOfLimes;

}

limesToCut(25, ['small', 'small', 'medium', 'large', 'small']);

@Ifycode it worked in the exercism editor.
but is there a way i can use a while loop and switch statement

[Danbaba1]

@Ifycode what about the third function in exercise 9

[Ifycode]

Well, there are two things I will say concerning this.

• Remember I said that I'm thinking if do-while or while loop is needed at all for this function. Probably it's the way I think about code. But I didn't see it working from start.
• Also, It's not compulsory that you use everything in the lessons in all the functions. Especially if using something will make it overly complex. That is what I feel about using those loops in this case.

But I could try again to see if a do-while or while loop would work. But definitely not with forEach, because it gives a wrong answer.

Ok, I was thinking that you said it's the 2nd function you are having problems with. So I didn't attempt that.

So try it out if you haven't. If you don't get it by tomorrow morning or noon, do this.

• Create a new branch from main
• In the new branch, create a file called 9.js, then copy and paste everything you have on your exercism editor in there.
• Send a pull request (no need to create another issue. Just link the pull request to this issue since it's still about learning exercise 9).

i was able to use a while loop with the second function on mixed juices exercise.

function limesToCut(wedgesNeeded,limes){
let limeCut = 0;
let wedgeCut = 0;
let index = 0;
let numLimes = 0;
while(index < limes.length){
switch(limes[index]){
case 'small':
wedgeCut = 6;
break;
case 'medium':
wedgeCut = 8;
break;
case 'large':
wedgeCut = 10;
break;
}
if(limeCut < wedgesNeeded){
limeCut += wedgeCut;
numLimes += 1;
}
index += 1;
}
return numLimes;
}
console.log(limesToCut(0,['small','small','large','medium','small']));

Nice work, well done @Danbaba1
I have written a reply to the comment on the PR for function 3. Pasting your code will give me a better idea of what you are struggling with.

@Ifycode thank you so much
