What is Caching in WordPress?

Caching is a technique used to store parts of your website temporarily, so it doesn't need to be fully loaded every time a visitor accesses it. By storing copies of web pages on a server or visitor's browser, cache speeds up loading times, leading to an improved user experience. However, cache can become outdated and cause performance issues, making it vital to know how to clear cache in WordPress.

Why Clear Cache in WordPress?
