Have you ever experienced a lag or delay when interacting with an interface on a web page? Perhaps it was typing in a search box, scrolling through a list of items, or resizing a window. These delays can be frustrating for users and negatively impact their overall experience.

This is where promise throttling and debouncing techniques come into play. By implementing them effectively, developers can significantly improve the responsiveness and efficiency of their applications.

Let’s dive into understanding what they are and how to use them in modern JavaScript development.

What Are Promises in JavaScript?

In JavaScript, promises represent values that may not be available yet but will be resolved at some point in time. They allow us to handle asynchronous operations more efficiently than using callback functions. A promise goes through three states during its lifetime: pending, fulfilled, and rejected. When working with multiple promises, we often need to manage their execution order, which leads us to our main topic — promise throttling and…
