Access Modifiers in OOP control the visibility of class members. There are four types: public, protected, private, and internal.
1. Public Access Modifier:
2. Private Access Modifier:
3. Protected Access Modifier:
4. Internal Access Modifier:
Client-side Example: ReactJS
In React, you can control component accessibility using JavaScript's export keyword.
Server-side Example: Node.js + Express:
In Express, access control can be managed in route handlers.
Database Example: MongoDB
MongoDB allows you to define field access within documents.
Best Practices
- Use the least restrictive access modifier needed.
- Encapsulate internal details to avoid unintended access.
- Consider security when exposing sensitive data.
- Maintain consistent access control across layers of your application.
