Event Handling vs Polling

Developers should learn event handling to build responsive and user-friendly applications that react dynamically to user interactions and system changes meets developers should use polling when building applications that need to monitor state changes, fetch updates from apis without websocket support, or in embedded systems where hardware constraints limit push-based methods. Here's our take.

Event Handling

Nice Pick

Developers should learn event handling to build responsive and user-friendly applications that react dynamically to user interactions and system changes

Pros

• It is essential for creating interactive features like form validation, button clicks, drag-and-drop interfaces, and real-time updates in web and mobile development
• Related to: javascript, dom-manipulation

Cons

• Specific tradeoffs depend on your use case

Polling

Developers should use polling when building applications that need to monitor state changes, fetch updates from APIs without WebSocket support, or in embedded systems where hardware constraints limit push-based methods

Pros

• It is particularly useful for simple monitoring tasks, such as checking for new messages in a chat app, tracking file upload progress, or querying sensor data in IoT devices, where low-frequency updates are acceptable and implementation simplicity is prioritized over efficiency
• Related to: long-polling, webhooks

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Event Handling if: You want it is essential for creating interactive features like form validation, button clicks, drag-and-drop interfaces, and real-time updates in web and mobile development and can live with specific tradeoffs depend on your use case.

Use Polling if: You prioritize it is particularly useful for simple monitoring tasks, such as checking for new messages in a chat app, tracking file upload progress, or querying sensor data in iot devices, where low-frequency updates are acceptable and implementation simplicity is prioritized over efficiency over what Event Handling offers.

The Bottom Line

Event Handling wins

Developers should learn event handling to build responsive and user-friendly applications that react dynamically to user interactions and system changes
