Debouncing in React is a technique used to limit the number of times a function is called in a specified time frame.
Debouncing helps in improving performance by reducing unnecessary function calls.
It is commonly used in scenarios like search bars where we want to wait for user to finish typing before making an API call.
Example: Using lodash debounce function to delay API call until user stops typing.
Throttling in React helps limit the number of times a function is called within a specified time frame.
Throttling is used to improve performance by reducing the number of times a function is executed.
It is commonly used in scenarios like handling scroll events or input changes.
Example: Using lodash's throttle function to limit the rate of execution of a function.
The question is unclear and seems unrelated to software development.
Ask for clarification on the question.
