create function to prevent duplication #36

Closed YuriDevAT closed 1 year ago

YuriDevAT commented 1 year ago

Description

The function created prevents from duplication of list items. Each tag can now only be added once.

This PR closes issue #12

Functionality

I am using the forEach() array function on the newly created list and compare the input I am going to make with all the list items already in the list. If the tag is in the list, then it is not added. If the tag is not in the list, then it is added.

Thoughts / Help

Actually, my first thought was using the include() function on the array stored in localStorage, but I could not make it work. My thoughts were: If the tag I want to enter in the input field is already in the list, then don't add it to the list.

I would love to get a hint in case my thoughts make sense and I simply made a mistake in the code, than I would give it another try. 🤗
