Cookie

The purpose of cookies is to bring state into stateless protocol which is HTTP.

In HTTP solely by including these cookies on request can identify us to the server.

Cookies are included on all HTTP request by default in header.

Also server can place information into the cookies so later on server can identify that client.

• Automatically included on all requests
• Unique to each domain ( cannot be shared)
• Cannot be sent to different domains

Token

• Have to manually wire up
• Can be sent to any domain

• dispatch : Makes sure the action gets sent to all reducers after sent through all different middlewares.

The main purpose of Redux Thunk is that we can directly access dispatch method.

Redux Thunk returns function instead of object from Action Creator. By returning a function we can directly access to the dispatch function. And inside of this function we can make any async requests, actions. So we can dispatch action anytime we want.

User on the website which has its own domain, sub-domain, port tries to make AJAX Request to different domain, sub-domain, port.

The purpose of CORS is soly for protecting the users in the browser

LocalStorage data is not shared across domains.

The same one with Redux Thunk dispatch is the property of Redux store 's dispatch.

Big solution for updating our app states before rendering any Components.
