Throttling is a technique that limits the rate at which a function is executed. In simple terms, it ensures that a function is called at most once within a specified time interval, regardless of how many times the event that triggers it occurs.
Key Benefits of Throttling:
Controlled Execution Rate: Ensures that a function does not execute more than the predefined rate.
Improved Performance: Reduces unnecessary load on both the client and server, enhancing overall performance and efficiency.
When to Use Throttling:
1. High-Frequency Events
Events like scroll, resize, and keypress can be triggered multiple times in a short period, sometimes unintentionally. This can lead to serious performance issues in the UI and backend. Throttling helps in controlling the rate at which the function is executed.
2. API Calls
Allowing users to make unlimited API requests can overwhelm the server with redundant or unnecessary requests. Throttling ensures that API calls are made at controlled intervals, preventing excessive network requests.
3. Animations and Transitions
Animations are resource-intensive. Applying throttling to animation-related event handlers prevents UI glitches and ensures smoother transitions.
4. Live Updates
For scenarios like live cricket score updates, where users might repeatedly click a refresh button, throttling prevents excessive data fetching and ensures updates occur at a controlled rate.
