Introduction to Debounce
• Debounce is a programming technique used to limit the rate at which
a function is called.
• It's particularly useful when a function might be invoked too
frequently, such as when handling user input events like keystrokes or
mouse movements.
• The primary goal of debouncing is to improve application
performance and responsiveness by preventing unnecessary load on
the system.
• Debounce prevents

Conclusion
• Debounce is a powerful tool for optimizing application performance.
• It helps reduce system load and improve the user experience.
• Proper use of debounce requires understanding its advantages and
limitations.
• Apply debounce in situations where you need to limit the rate of
function calls triggered by user input events.
• Try implementing debounce in your projects!
Debounce is a crucial performance optimization
technique that should be applied in appropriate
scenarios to create more efficient and responsive
applications.
