In class components, where is the best place to set the initial state?

In the constructor.
In the componentDidMount lifecycle method.
In the render method.
In an external configuration file.

In class components, the best place to set the initial state is in the constructor. This is because the constructor is called before the component is mounted, and you can initialize the state object there. Setting the initial state in other methods may lead to unexpected behavior. The other options are not the recommended places for setting the initial state.
