Is react fast?
React is generally fast, but by default any updates to a component will cause React to re-render all of the components inside that part of the component tree. This does require work, and if the data for a given component hasn't changed, then re-rendering is likely some wasted effort because the requested UI output would be the same.

Actions are simply events that are created using functions and send data from the application to the store. Data may be sent via different ways such as submitting a form, calling an API or basic user interaction.
