Summarize this article for a 10 years old


WebKit is a browser engine developed by Apple and primarily used in its Safari web browser, as well as all web browsers on iOS and iPadOS. WebKit is also used by the PlayStation consoles beginning from the PS3, the Tizen mobile operating systems, the Amazon Kindle e-book reader, Nintendo consoles beginning from the 3DS Internet Browser, and the discontinued BlackBerry Browser. WebKit's C++ application programming interface (API) provides a set of classes to display Web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited.
