What does setState do?

• Component State – React

setState() schedules an update to a component's state object. When state changes, the component re-renders.

What is the difference between state and props?

props (short for properties) and state are both plain JavaScript objects.

While both hold information that influences the output of render, they are different in one important way.

• props get passed to the component (similar to function parameters), whereas
• state is managed within the component (similar to variables declared within a function).
