Which of the following is NOT true regarding error boundaries?
- Error boundaries are defined using the try...catch statement.
- Error boundaries can be nested within other error boundaries.
- Error boundaries can replace the entire component tree.
- Error boundaries catch errors in child components.
The statement "Error boundaries are defined using the try...catch statement" is NOT true. Error boundaries in React are defined using special error boundary components and not the traditional try...catch statement. Error boundaries use the componentDidCatch() method to catch errors in child components and provide a graceful way to handle them. They can also replace parts of the component tree but are not defined using traditional error-handling syntax.
