When to make a React component a class or a simple object?
In the React Redux tutorials, when creating separate components to handle different functionality of the scoreboard, some of the components are defined inside a class, like 'AddPlayerForm' and others are simple functions stored in a 'const' variable inside their own files. Any more clarification as to why they are defined differently (class vs const variable)?

Currently while everything is still being compiled to es5 with babel there is no advantage of using a stateless function over a class although many people prefer to use them when possible as its quite clean syntax. You cannot use a stateless function and must use a class if you need to use any of the lifecycle methods or if you need to store state in your component. In the future when es6 is implemented natively it may be more performant to use stateless functions instead of classes where possible.
