OpenID is an open standard used for authenticating users through OpenID service providers also known as OpenID providers such as Google, Facebook, Twitter used in authentication.
For example, application A forwards the user to an OpenID provider URL for login. If successfully logged in, OpenID Provider will forward the user to the page of Application A and notify this application that user U has been authenticated. Finally, Application A performs the authentication of user U without logging in because A believes in the result returned by the OpenID Provider.
OAuth is an open standard used in giving permission for an application (client) to access services from another application (service provider). For example, when you are asked by an application A (or client A) to provide information such as email, first and last name, place of birth, and occupation from your Facebook (service provider) account.
Now, if you give Application A the right to retrieve the above information, the Facebook service provider will allow A to retrieve this information stored on Facebook’s server.

Main concepts you need to know before start coding React:
State – The data that is created and managed by components. In State, data can only be created, managed, and modified but not passed or transferred.
Props – The data that is passed from parent component to child is called Props (Properties). Data from Props is read-only, and cannot be modified by a component which differs from State.
