Front-end performance optimization | Anti-shake and throttling

1. Foreword Why do we need to optimize performance? How important is performance optimization? Excellent performance is to provide a better user experience, speed up website loading, improve search engine ranking, save Server resources, Adapt to various devices and network environments, etc. By continuously optimizing performance, user satisfaction can be improved, website traffic can be […]

05.JavaScript (anti-shake throttling, video playback and positioning of the last position)

Anti-shake throttling Anti-shake (debounce) The so-called anti-shake means that the function can only be executed once within n seconds after the event is triggered. If the event is triggered again within n seconds, the function execution time will be recalculated. Throttle The so-called throttling means that events are triggered continuously but the function is only […]

Throttling and debouncing

1. Concept Throttling and debouncing are two performance optimization techniques commonly used when handling user input and other events. Their main purpose is to control the frequency of event triggering to avoid unnecessary repeated operations, reduce system burden, and improve user experience. 1.Throttling: Throttling is a technique that limits the execution frequency of event handling […]

js advanced (proxy, shallow copy, deep copy, throttling and anti-shake, closure.hasOwnProperty)

1.Agent 1. Question: How to define an object that will not be modified or traversed? Define default properties through Object.defineProperty(object, property name, option) cannot be modified cannot be deleted cannot be traversed Note: The value passed in by Object.Property and the value returned are the same address You can configure the properties value: initial value […]

ByteDian: Can you cut it with your hands to reduce throttling and prevent shake?

Foreword Recently, a blogger encountered such an interview question in Byte Interview. This question is also a high-frequency question in front-end interviews. Throttling and anti-shake are a very important means of front-end performance optimization, so as a front-end Engineers must master this knowledge point in depth. The blogger will explain it in detail here. About […]

How to accurately master the use of function anti-shake and function throttling?

Preamble Function debouncing (Debouncing) and function throttling (Throttling) are both technologies used to control the execution frequency of functions. They are usually very useful when processing high-frequency triggered events (such as window scrolling, mouse movement, input box input, etc.) 1. Core concepts Function anti-shake The core idea of function anti-shake is that when an event […]

js performance optimization: thoroughly understand function anti-shake and function throttling

Function anti-shake and throttling Function anti-shake and function throttling: A means to optimize high-frequency execution of js code. When some events in js, such as browser resize, scroll, mousemove, mouseover, and input box keypress, are triggered, they will Continuously calling the callback function bound to the event greatly wastes resources and reduces front-end performance. In […]

Kubernetes OOM and CPU Throttling Issues

Introduction Out of memory (OOM) errors and CPU throttling (Throttling) are major pain points for resource handling in cloud applications when using Kubernetes. why? CPU and memory requirements in cloud applications are becoming increasingly important because they are directly related to your cloud costs. With limits and requests, you can configure how pods should allocate […]
