💠React Interview Question: What Are Higher-Order Components (HOCs)?

Imagine you’re taking a photograph 📸. The original photo is beautiful on its own, but sometimes, you might want to apply a filter to enhance it — maybe to add warmth, increase contrast, or create a vintage effect.

In React, Higher-Order Components (HOCs) work similarly. They’re like filters for your components, adding extra effects or functionalities without changing the core component.

Just like applying a filter to a photo can transform its look and feel, an HOC can wrap around a component to enhance its behavior, making it even more versatile.

🔍 What is an HOC?

🔹An HOC is a function that takes a component as an argument and returns a new, enhanced component. It’s the React way of reusing component logic across different parts of your application.

🔹For example, applying a “vintage” filter to a photo adds a warm, nostalgic tone. Similarly, an HOC can add new props, handle conditional rendering, or modify how a component behaves based on the context.

💡 Why use HOCs?

🔹 Code Reusability : HOCs allow you to reuse logic across multiple components.

🔹Separation of Concerns : Keep your component code clean and focused on its core role.

🔹Scalability : Modularize and reuse functionalities easily.

Just as you’d choose the right filter to bring out the best in a photo, use HOCs to make your components shine even brighter! 🌟
