Actions

Actions are simple objects containing information that sends data from your app over to the app's store. All the logic that your app handles will pass through the action - your store never receives any data from sources that aren't actions.

An action requires a type property, which defines the type of user action that has occurred. Types of actions are represented in a stringified form. They can be hardcoded into the object itself or passed in as a constant. For example:

export function addTask(taskName) { 
  return { 
    type: 'ADD_TASK', 
    taskName: taskName 
  } 
} 
 
// With constants 
 
const ADD_TASK = 'ADD_TASK'; 
 
export function addTask(taskName) { 
  return { 
    type: ADD_TASK, 
    taskName: taskName 
  } 
} 

These functions will be made available as props ...
