How and when to debounce or throttle in React

The text explores the challenges of real-time data filtering in applications, specifically when handling large datasets, and offers solutions using debouncing and throttling techniques in React. It highlights how event listeners can cause application unresponsiveness by triggering multiple processes simultaneously, using the example of filtering a list of over 70,000 cities as a user types. Debouncing is explained as a method to delay function execution, allowing input completion before initiating a new process, while throttling limits function execution to once within a specified period. The text details practical implementations using JavaScript's setTimeout and clearTimeout methods, Lodash's debounce and throttle functions, and the react-debounce-input package, emphasizing the importance of choosing the simplest effective solution for specific use cases.
