The “vanilla” store implementation you get by calling createStore only supports plain object actions and hands them immediately to the reducer.
However, if you wrap createStore with applyMiddleware, the middleware can interpret actions differently, and provide support for dispatching async actions. Async actions are usually asynchronous primitives like Promises, Observables, or thunks.
This essay attempts to make Conal’s vision more understandable to less mathematically-oriented programmers, and also show how this perspective could be the foundation for a new era of programming, not just with user interfaces, but also multi-node computing, storage, machine learning, etc.

Governments are back on their anti-encryption bullshit again. Between the U.S. Senate's "EARN IT" Act, the E.U.'s slew of anti-encryption proposals, and Australia's new anti-encryption law, it's become clear that the authoritarians in office view online privacy as a threat to their existence. Normally, when the governments increase their anti-privacy sabre-rattling, technologists start talking more…

- Integration tests strike a great balance on the trade-offs between confidence and speed/expense. This is why it's advisable to spend most (not all, mind you) of your effort there.
- biggest thing you can do to write more integration tests is to stop mocking so much stuff
- When you mock something you're removing all confidence in the integration between what you're testing and what's being mocked.
