Javascript: subLength() code challenge

Get Help JavaScript
#1

Hi all! I’m new at coding and I have encountered a code challenge that I can’t solve. My code is returning the “correct” values as far as I can tell, but it is not passing the exercise. Any help would be highly appreciated.

My code is pasted below:

let counter=0;
let result=0;

const subLength = (str,char) => {
  
  // split into string array
  stringArray=str.toLowerCase().split('');

  // count the repetitions
  stringArray.forEach(item => {
    if (item === char){
      counter++;
    }
  })

  // evaluate if num of reps is 2
  if (counter === 2) {
    result = stringArray.lastIndexOf(char)-stringArray.indexOf(char)+1
  } 
  
   // set result to 0 if not right amount of reps
    else if (counter != 2){
    result = 0;
  }

  return result;
}

When I test my code using console.log(subLength(‘funny’,‘n’)) it prints 2 to the console. However, when I click ‘check answer’ it gives me the error Tested subLength('funny', 'n') and it did not return 2 . Can you help me understand what went wrong in my code?

Try testing your code more than once with the same input (without restarting the program).

console.log(subLength("funny", "n"));
console.log(subLength("funny", "n"));

Thank you very much! You made me realize I had placed the variable declarations incorrectly. It worked as soon as I placed them within the function. I really appreciate the help.
