localStorage is only capable of storing string values so what you've got there is an array, serialised to JSON.

To remove elements from it, you'll need to

  1. Parse the string as JSON to an array
  2. Remove the item
  3. Stringify the array and put it back in localStorage
const tags = JSON.parse(localStorage.tags ?? "[]")
localStorage.tags = JSON.stringify(tags.slice(0, -1))

You can of course single-line this

localStorage.tags = JSON.stringify(JSON.parse(localStorage.tags ?? "[]").slice(0, -1))
