Reducer Example

reducer.js

/* Create A Reducer
 *
 * You need to create a reducer called "appReducer" that accepts two arguments:
 * - First, an array containing information about ice cream 
 * - Second, an object with a 'DELETE_FLAVOR' `type` key
 * (i.e., the object contains information to delete the flavor from the state)
 *
 * The action your reducer will receive will look like this:
 * { type: 'DELETE_FLAVOR', flavor: 'Vanilla' }
 *
 * And the initial state will look something like this (as such, refrain 
 * from passing in default values for any parameters!):
 * [{ flavor: 'Chocolate', count: 36 }, { flavor: 'Vanilla', count: 210 }];
*/
const DELETE_FLAVOR = 'DELETE_FLAVOR';

function myAction(flavor) {
  return {
      type: DELETE_FLAVOR,
        flavor
  }
};
function addTodo(text) {
  return {
    type: ADD_TODO,
    text
  }
}
function appReducer (state = {}, action) {
    if(action.type == DELETE_FLAVOR) {
        return action
    }
    return state
    
}

console.log(appReducer({}, myAction(‘Vanilla')));
