[英]What does { [native code] } mean in WebKit's Inspector?
For instance, open up a JS console, and type toString<Enter>
. 例如,打开一个JS控制台,然后键入
toString<Enter>
。
You'll get this: 您将获得:
function toString() { [native code] }
Contrast this with: 将此与:
function foo() { return 'bar'; }
foo
which produces: 产生:
function foo() { return 'bar'; }
Does it mean that its an API to the interpreter which directly executes some internal routines in C or whatever is used to program it when that method is called? 这是否意味着它是解释器的API,该解释器直接在C中执行一些内部例程,或者在调用该方法时使用了用于对其进行编程的任何方法?
