Solve the problem -Redux: Register a Store Listener

Tell us what’s happening:

Your code so far


const ADD = 'ADD';

const reducer = (state = 0, action) => {
switch(action.type) {
  case ADD:
    return state + 1;
  default:
    return state;
}
};

const store = Redux.createStore(reducer);

let carIsBroken = true;
const callCarOwner = () => console.log("Hello your car is done!");
const fixCar = (carIsBroken, callCarOwner) => {
if (carIsBroken === true) {
  carIsBroken = false;
}
console.log(carIsBroken);
// After the car is fixed, the last thing we do is call the car owner - that's our 'callback function'.
callCarOwner();
};
fixCar(carIsBroken, callCarOwner);
let count = 1;
const addOne = () => (count += 1);
function sayHi(addOne) {
return count;
}
store.subscribe(sayHi);
// change code above this line

store.dispatch({type: ADD});
console.log(count);
store.dispatch({type: ADD});
console.log(count);
store.dispatch({type: ADD});
console.log(count);
