Ways to Determine If An Item Exists

1

My question is why does my code (which uses ingredientList[ingredientToSearchFor] !== undefined) isn’t accepted (the answer is ingredientList.indexOf(ingredientToSearchFor) > - 1). Don’t these mean the same thing?

2

Is ingredientList an object or an array?

ingredientList[ingredientToSearchFor]

will look for a property in an object.
