Why is a component constructor called only once?

The constructor is called for each new instance of the component
The constructor is not needed in functional components
The constructor is not used in React components
The constructor is only called when the component is first created

In React, the constructor is called only once when the component is first created. This is because the constructor is used to initialize the component state and bind event handlers, and these operations only need to be performed once. After the component has been created, subsequent updates will use the "componentDidUpdate()" method to update the state and re-render the component.
