When to use Pure Components?
- Expensive Rendering Logic: Use Pure Components when the component’s rendering logic is expensive or time-consuming to optimize performance.
- Predictable Props and State Changes: If the component’s props and state changes are predictable and it should only re-render when those changes occur, Pure Components ensure efficient rendering.
- Minimizing Re-renders: Pure Components are ideal for minimizing unnecessary re-renders in your application to improve overall performance.
Example:
import React, { PureComponent } from 'react';
class Pure extends PureComponent {
render() {
return <div>Pure Component</div>;
}
}
Output:
How does a Pure Component Differ from a Regular Component ?
