Basic Data Structures - Check For The Presence of an Element With indexOf()

Curriculum Help
1

I used if-else to check the index of array elements, and it does work, but it is not passing all the test case.
Please check my code and tell me where I need to improve.

Your code so far

function quickCheck(arr, elem) {
  // Only change code below this line
  if(arr.indexOf(elem)){
    return true;
  }else{
    return false;
  }
  // Only change code above this line
}

console.log(quickCheck(['squash', 'onions', 'shallots'], 'mushrooms'));

indexOf returns a number. Either the index position of the element or -1 if it doesn’t find the element. Its return value is not suited for boolean coercion. Check the return value is >= 0

If you wanted to use the logic you have you would use includes which returns true or false.
