Let's install PostgreSQL onto your operating system.

As an open source object-relational database management system, PostgreSQL available for MacOS, Linux, and Windows.

Goal for each Operating System

The goal will be to run the following command successfully from the command line (regardless of the OS):

psql -U postgres

This should open the psql interactive shell and print a prompt that looks like:

The bindActionCreators utility was specifically created for cases like binding methods for use in React components. In fact, straight from the bindActionCreators API reference:

The only use case for bindActionCreators is when you want to pass some action creators down to a component that isn't aware of Redux, and you don't want to pass dispatch or the Redux store to it.

Personally, though, I advise using the object shorthand argument for connect, instead of writing your own mapDispatch function. The object shorthand will automatically call bindActionCreators for you, and it's one less thing to worry about:

export default connect(mapState, {addTodo, toggleTodo})(TodoList);
So no, bindActionCreators isn't a "dangerous" pattern, and I highly recommend binding action creators so that your components aren't "aware" of Redux. When a component calls this.props.someFunction(), it shouldn't know or care whether that method is a callback from a parent component, a bound-up Redux action creator, or a mock function in
