Debouncing is a technique used to ensure that a function doesn't get called too frequently.
It's commonly employed in scenarios where we want to wait for a pause in user input before triggering an action.
For example, in search bars, debounce delays the execution of the search function until the user has finished typing, preventing unnecessary API requests with each keystroke.
Throttling, on the other hand, limits the maximum number of times a function can be called over a certain period.
It's useful in scenarios like handling scroll events, where we want to limit the rate of function execution to improve performance.
For instance, in infinite scroll or lazy loading implementations, throttling ensures that the content loads gradually, preventing excessive resource consumption and improving user experience.
The decision between debounce and throttling depends on the specific requirements of the use case.
If the goal is to respond to every event but only after a certain quiet period following the last event, debounce is suitable.
Conversely, if the objective is to limit the rate of function execution, especially to prevent performance issues, throttling is preferred.
It's akin to choosing between immediate response (debounce) or controlled execution rate (throttling) based on the context and desired behavior.
Debounce is commonly applied in scenarios where precise user input handling is required, such as search bars or form validation.
Throttling is often used in scenarios where we want to control the frequency of event handling, such as scroll or resize events, to ensure optimal performance and resource utilization.
Understanding the nuances of debounce and throttling empowers developers to efficiently manage event handling and optimize application performance.
