Difference between declarative and imperative programming?
React supports declarative programming.
A declarative style, like what react has, allows you to control flow and state in your application by describing 'It should look like this!'. An imperative style turns that around and allows you to control your application by saying 'This is what you should do'.
The benefit of declarative is that you don't get bogged down in the implementation details of representing the state. You're delegating the organizational component of keeping your application views consistent so you just have to worry about state.
A real-life parallel in the imperative world would be entering a bar for a beer, and giving the following instructions to the bartender:
- Take a glass from the shelf.
- Put the glass in front of the draft.
- Pull down the handle until the glass is full.
- Pass me the glass.
In the declarative world, instead, you would just say: "Beer, please."
