In web development, dynamically removing loaded JS code is an important optimization technique, which can effectively improve page performance, reduce memory usage, and avoid potential JS conflicts. This article will delve into several commonly used methods, including directly manipulating DOM elements, using JavaScript garbage collection mechanisms, and using Web Workers to isolate scripts, etc., and analyze their advantages, disadvantages, and applicable scenarios to help you better understand and apply this technology.
To dynamically remove loaded JS code, you first need to understand that this operation mainly helps to improve page performance, reduce memory usage, and prevent possible JS conflicts. Core methods include: directly operating DOM elements to remove script tags, using JavaScript's garbage collection mechanism, and using Web Workers to isolate scripts.
