Filter is not working inside the action for filtering array of objects in Vuex

问题

I have an array of objects which is getter. I am using getter inside action and trying to filter it but whatever I do filtering doesn't work and it returns all mapped item ids.

filterItems({ getters, commit }) {
  let filteredItems = getters.getAllItems
    .filter(item => item.type !== 'hat' || item.type !== 'glases')
    .map(item => item.id)
  console.log(filterItems)
  commit('setFilteredItems', filteredItems)
},

What is wrong?

回答1:

I think the problem is coming from here:

item.type !== 'hat' || item.type !== 'glases'

1. This always returns true because item.type will never be equivalent to 'hat' and 'glases' at the same time.
2. I doubt that 'glases' is a correct spelling? This might be a problem or just a mis-typing
