What are debouncing and throttling in React?

What are debouncing and throttling in React?

Debouncing and throttling are techniques used to control the rate at which a function is executed in response to events. In React, they help improve performance by limiting the number of times a function is called during rapid events like scrolling or typing.

Can you explain how debouncing works with an example?

Sure! Debouncing ensures that a function is only called after a specified delay. For example, if you have an input field that triggers a search on every keystroke, debouncing can delay the search function until the user stops typing for a certain period.

What about throttling? How is it different from debouncing?

Throttling, on the other hand, ensures that a function is called at most once in a specified time interval. For instance, if you want to limit a scroll event handler to execute every 200 milliseconds, throttling would achieve that.

When should I use debouncing over throttling?

Use debouncing when you want to wait for a pause in activity, like user input. Use throttling when you want to ensure a function runs at regular intervals, like during scrolling.
