📑 object expression

It’s important to wrap it in parents, so that parser understands this as an expression rather than a block.

Also, it can be nicer to use the concise method notation inside mapdispatchtoprops, instead of arrow functions because it’s harder.

const mapDispatchToProps = (dispatch) => ({
	onTodoClick(id) {
		dispatch({ type: "TOGGLE_TODO", id });
	},
});
