Tell us what’s happening:
Even after following the instructions and passing a listener function, the test case still fails saying There should be a listener function subscribed to the store using store.subscribe.
I have gone through the hint ,tried arrow and normal function.
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);
// Global count variable:
let count = 0;
// Change code below this line
function listener () {
count+=1;
}
store.subscribe (listener);
// 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);
