+- Limiting the frequency of function calls in response to rapidly occurring events like scrolling, resizing, or key presses.
+- Ensuring a function is not executed more than once within a specified time interval to optimize performance.
+- Delaying execution of repeated function calls but allowing a final trailing call to execute after the last event in some cases.
+- Useful for scenarios like logging, network requests, or animation triggers that shouldn't be triggered too frequently.
