How to change an array from Vuex from a variable and put it back?

Question

Vue.js

Plz tell me, i'm facing the same problem. There is an array in the vuex storage, which I get in the component through a getter (everything is as it should be) and save it to a variable, then when in the function I start working with a new variable and change the order of the objects in this array (so that I can then put the changed array) then I immediately get an error in the console
Error: [vuex] do not mutate vuex store state outside mutation handlers.
How can I change this array correctly? so that there are no errors?

Answer 1

Translate error text and don't do so

Answer 2

You need to read about mutations and actions. Everything will become clear right away.
