How can I improve the performance of asynchronous JavaScript?

To improve asynchronous JavaScript performance, consider using techniques like debouncing, throttling, and optimizing your promises.

What is debouncing and how does it help?

Debouncing is a technique that limits the rate at which a function is executed. It helps by reducing the number of times a function is called, especially during events like scrolling or resizing.

Can you give me an example of throttling?

Sure! Throttling ensures a function is only called at most once in a specified time period. For example, if you want to limit a scroll event handler to run every 100 milliseconds, you can use a throttling function.

What are some common pitfalls to avoid with async code?

Common pitfalls include not handling errors properly, creating too many concurrent requests, and forgetting to await promises, which can lead to unexpected behavior.
