In Javascript, all function arguments are optional by default. That means if you ever forget to pass a critical parameter, the code will just fail without warning you what went wrong.

Redux is one of the most popular state-management libraries and although not specific to React, it is widely used with it. This is why the author of Preact has released a package called preact-redux, which is a simple wrapper around the main react-redux package that enables it to be used in a Preact application without any other changes to your codebase. In this lesson we refactor a stateful component to use Redux + Redux-thunk. https://github.com/developit/preact-redux
