In each subfolder you'll find a simple Redux application, each with a fully implemented render method. You might find these render methods familiar; they're the same examples from your prior rendering exercises. You'll be writing the Redux data-layer for each of these examples.
As you write your reducers, keep this in mind: Redux requires you to write a pure reducer. That means your reducers can't mutate the state object that gets passed in!
const initialState = { value: 0 };
const reducer = (state = initialState, action) => {
const { type } = action;
if (type === "INCREMENT") {
state.value++;
return state;
}
return state;
}const initialState = { value: 0 };
const reducer = (state = initialState, action) => {
const { type } = action;
if (type === "INCREMENT") {
return {
value: state.value + 1
};
}
return state;
}
