[TIL] React 재학습 - immer

typescript에서 immer를 사용하기

import { produce } from 'immer';

...
  initialState = {
    immerTest: {
      key2: ["value1", "value2"],
    }
  },
  ...
  immerTest: (state) => {
    state.immerTest = produce<any>(state.immerTest, (draftState) => {
      draftState.key2.push("hello");
    }
  }
