What is the most efficient way to remove an object from an array in Vuex?

Question

Vue.js

1 option

mutation(state, { id }) {
  state.arr = state.arr.filter(item => item.id != id)
}

Option 2

mutation(state, { id }) {
  Vue.delete(state.arr, state.arr.findIndex(item => item.id == id))
}

Answer 1

Both options are about the same - the speed of searching for an index to delete will be O (N). The most efficient option is to use an object with id keys, then the lookup speed is O(1).
