A brief analysis of the difference between arguments and arguments.callee in Javascript_Basic knowledge

Let’s understand the specific difference between arguments and arguments.callee through an example:

The code is as follows:

Copy code The code is as follows:

Calling method:

Copy code

The code is as follows:

The result after running is:

Copy code

The code is as follows: ac:2 ex:3

wrong number of arguments: expected: 3; actually passed2

NaN



My understanding:

arguments is the calling object, which is the object that calls this method arguments.callee is the current object, which actually returns the currently executed function object

Through this example, we can see that

arguments actually refers to the function "f(1,2)"

argument.callee actually refers to "function f(x,y,z){}"
