How do you connect frontend to backend?
In respect to this, how does front end interact with backend?
Backend code is built to be running on a server and it's never running on the user's machine. Frontend - the parts of your web application which are intended to be used directly by the the user's browser. Code which is executed inside the browser, or markup which is interpreted while rendering a page.
In respect to this, can React be used for backend?
No. React is a Front end Javascript library, it is not even a framework. React is capable of making API calls (send request to backend), which deals with the data. React cannot deal with database or any datasource itself.
Also often called Mobile Backend as a Service, BaaS, or MBaaS, an API backend is a way for developers to link their software and application to cloud-based storage, making it easier to link up with software development kits and APIs.
