What is the difference between dispatch() and a normal function call with dispatches inside?

Question

React

Everywhere they write that redux-thunk makes dispatches asynchronous, but without them, a function with the same asynchronous dispatches can be called on an event. What's the catch? And why are they even needed then?

Answer 1

As soon as you take the function that performs the asynchronous action outside the component, you will need to manually forward dispatch and getState into it. redux-thunk does this for you.
