User Scripts
User Scripts are small pieces of JavaScript code that users can install in their web browsers to modify the appearance, behavior, or content of websites. They run on top of web pages and allow for customization, automation, and enhancement of the browsing experience without requiring changes to the website's original code. This technology is commonly used for tasks like blocking ads, adding features, or scraping data.
Developers should learn User Scripts when they need to automate repetitive web tasks, customize websites for personal or client use, or build lightweight browser extensions. They are particularly useful for web scraping, testing, accessibility improvements, and creating productivity tools that interact with specific sites, as they provide a quick way to inject functionality without deep browser API knowledge.
