6. Best Practices for Using super()
and super(props)
To ensure optimal code structure and maintainability, it is essential to follow some best practices when using super()
and super(props)
in React:
- Always invoke
super()
as the first line of code in the child class’s constructor to call the parent class’s constructor before initializing any child-specific properties. - When passing props to the parent class, use
super(props)
in the child class’s constructor to enable seamless data flow between components. - Avoid excessive reliance on inheritance and favor composition and component reusability to keep your codebase modular and maintainable.
