JavaScript Knowledge Event Loop, Closures, Promises, Prototypal Inheritance, Debounce and Throttling, Modularization, Deep and Shallow Copy, Event Delegation, Garbage Collection, and the this Keyword
1. Event loop The event loop is the core mechanism of the JavaScript runtime environment, which is responsible for handling asynchronous tasks, such as setTimeout, setInterval, and various I/O operations. JavaScript is single-threaded, which means it can only handle one task at a time. In order to achieve asynchronous operations, the event loop divides tasks […]
SpringBoot uses Redis cache, combined with Aop and custom annotations to achieve interface throttling
A Programmer’s Path to Growth Internet/Programmer/Technology/Data Sharing focus on It will take about 2.8 minutes to read this article. From: blog.csdn.net/m0_59588838/article/details/128458761 Interface throttling is a business requirement during the development process to prevent a single microservice module from suddenly experiencing too much concurrency and resulting in unsmooth user services, that is, to achieve a fixed […]

45. Current limiting Throttling and source code analysis
What is current limiting? Current limiting is similar to the permission mechanism. It also decides whether to accept the current request, and is used to control the number of times the client is allowed to make requests to the API within a certain period of time, that is, the frequency Assuming that a client (such […]
Flutter – implement anti-shake and throttling
demo address: https://github.com/iotjin/jh_flutter_demo The code is updated from time to time, please go to github to view the latest code What are anti-shake and throttling? Function throttling (throttle) and function anti-shake (debounce) are both to limit the execution frequency of the function to optimize the response speed caused by the high trigger frequency of the […]
