Use the placeholder attribute rather than the value attribute to avoid accidentally submitting placeholder values.
HTML forms can send POST requests without the help of JavaScript.
Use POST, not PUT, to add items to the produce list.
Not every property of new produce item needs to be required. However we do need itemCondition since it is one of the values we search over.

Update the "database" by adding the newly created produce item.
Use the correct name for the filtering & sorting function.
