Scroll-Driven Animations Inside a CSS Carousel
Article Introduction：Hey, isn't there a fairly new CSS feature that works with scroll regions? Oh yes, that's Scroll-Driven Animations. Shouldn't that mean we can trigger an animation while scrolling through the items in a CSS carousel?

How to implement infinite scrolling
Article Introduction：The key to achieving infinite scrolling is to listen to scroll events and trigger loading. The core steps include: 1. By listening to scroll events and calculating the scroll position, judging whether it bottoms out; 2. Use throttling and locking mechanisms to prevent duplicate requests; 3. After loading the data, update the DOM and page height and handle the boundary situation; 4. Optionally use IntersectionObserver to improve performance. The specific method is to use JavaScript to monitor the scroll position, load new content when it is close to the bottom, add a buffer to avoid blanks, and set the isLoading flag and throttle to control the request frequency. After the data is loaded, update the container height and check whether there is more data. You can also add loading animation optimization experience.

jQuery Detect % Scrolled on Page
Article Introduction：Detect web page scrolling percentage using jQuery
The following jQuery code snippet demonstrates how to trigger an event action when a user scrolls to a specific percentage of the webpage. Tests show that when capturing mouse scroll events, it is best to use values ??between 55% and 100%.
$(document).ready(function(){
// Example: Show a div when scrolling to 75% of the web page
var webpage = $("body");
var webpage_height = webpage.height();
var trigger_height = webpage_hei

How to optimize JavaScript execution time
Article Introduction：The key to optimizing JavaScript execution time is to reduce main thread blocking, reasonably control execution frequency, reduce DOM operations and utilize efficient data structures. 1. Split or move the time-consuming task to WebWorker to avoid lag on the main thread; 2. Use anti-shake and throttling to control the trigger frequency of high-frequency events, such as resize, scroll, etc.; 3. Cache DOM status, batch update content, and give priority to DocumentFragment; 4. Use native methods (such as map, filter) and appropriate data structures (such as Set, Map), and consider typed arrays when processing big data. These methods can effectively improve page response speed and user experience.

Debouncing and Throttling Functions for Performance Optimization in JavaScript
Article Introduction：Debounce and throttle are two technologies that optimize the execution frequency of high-frequency events in JavaScript. 1. The core of Debounce is that it only executes the last time after multiple triggers, which is suitable for scenes where input box search, window adjustment, etc. that need to wait for stop operation; 2. The core of Throttle is that it only executes once within a fixed time interval, which is suitable for scenes where scroll monitoring, mouse movement and other scenarios that need to limit the frequency of execution. The difference between the two lies in the triggering timing and applicable situation: the debounce is executed after the trigger is stopped, and the throttle is executed periodically. When using it, you need to pay attention to the functions of context binding, parameter passing and optional immediate execution, and can be implemented with the help of the Lodash library.
