lists don't clear for some reason even though it's written correctly

Question

//clearing lists
function resetLists() {
 var finalColor = [];
 var finalDiet = [];
 var finalConservationStatues = [];
 var finalScientificName = [];
 var finalName = [];
}

this should be clearing/resetting the lists but it doesn't when called on in the program.I have tried calling the function in different parts of the program but it still doesn't work

If those variables are global, the following should work:

//clearing lists
function resetLists() {
 finalColor = [];
 finalDiet = [];
 finalConservationStatues = [];
 finalScientificName = [];
 finalName = [];
}

However, you can first test if the function can even "see" the variables you want to clear by adding a quick debug statement:

//clearing lists
function resetLists() {
 console.log("DEBUG: Can I see the following?");
 console.log(finalColor);

 finalColor = [];
 finalDiet = [];
 finalConservationStatues = [];
 finalScientificName = [];
 finalName = [];
}

lists don't clear for some reason even though it's written correctly
