如何在redux中从数组中删除对象

export default function(state={inputs:[ ]}, action) {
        console.log(action.index);
        switch (action.type) {
        case APPEND_INPUT:
            return { ...state, inputs: state.inputs.concat({value:"",key:"1",type:'input'})};
        case APPEND_TEXTAREA:
            return { ...state, inputs: state.inputs.concat({value:"",key:"",type:'textarea'})};
        case APPEND_EMAIL:
            return { ...state, inputs: state.inputs.concat({value:"",key:"",type:'email'})};
        case REMOVE_INPUT:
            return  {inputs: state.inputs.slice(0)};

        default:
            return state;
        }
    }

{inputs: state.inputs.filter((_, i) => i !== action.index))
