Tell us what’s happening:

const immutableReducer = (state = [0,1,2,3,4,5], action) => {
switch(action.type) {
case ‘REMOVE_ITEM’:
// don’t mutate state here or the tests will fail
return
default:
return state;
}
};

const removeItem = (index) => {
return {
type: ‘REMOVE_ITEM’,
index
}
}

const store = Redux.createStore(immutableReducer);

Your code so far


const immutableReducer = (state = [0,1,2,3,4,5], action) => {
switch(action.type) {
  case 'REMOVE_ITEM':
    const newState = state.filter( val => val !== action.index );
   
    return newState;
  default:
    return state;
}
};

const removeItem = (index) => {
return {
  type: 'REMOVE_ITEM',
  index
}
}

const store = Redux.createStore(immutableReducer);

You should use the second argument of .filter() for comparing:

const newState = state.filter( (val, index) => index !== action.index );
