What JavaScript engine does Apple's Safari browser use?

Question

I found out from the Internet that Google Chrome uses V8 and Firefox uses SpyderMonkey to compile JavaScript to machine code. What JavaScript engine does Safari browser use then?

JavaScriptCore is the built-in JavaScript engine for WebKit.

JavaScriptCore is often referred with different names, such as SquirrelFish and SquirrelFish Extreme. Within the context of Safari, Nitro and Nitro Extreme are also commonly used. However, the name of the project and the library is always JavaScriptCore.
