rinds | R package for the book R in data science

Basically, I use the innerText of each html element as keys in the object

On a side note: only Pulled Pork Nachos, 6 Wings and Pork Rinds have any relation in the food variable so it will work better when you use your full variable and not JUST these 3 indexes(for an item that is non-existent in the food variable, an alert is shown)

NOW as to what I fully did:

FIRSTLY, I made 3 variables outside the function; blankElemState which is the tab element's innerHTML when holding NOTHING, amount as TOTAL tab amount and purchases for holding the object equivalent of each purchase(because of reference logic, one can search through the food, drink and merch arrays and when a value EQUALS a value in purchases, that's the exact item of purchase). For example of the reference logic, purchases[8] might EQUAL food[2]

SECONDLY, I made a variable i that holds the place in the food array of the requested item(for drinks you can change that part to drinks.forEach instead of food.forEach and so forth).

NEXT, if there is nothing in the array that refers to the requested item(by user), I warn that there is nothing available for the order(which naturally should not happen).

THEN, if tabAmountSection already has elements appended to it(not equal to blankElemState), I clear tabAmountSection(by making its innerHTML back to blankElemState) so that there aren't multiple "final" purchase values and remove buttons
