除了递归调用本身之外，还有其他命名正在分配的 function 的用途吗？

Question

If I say:

let F = function G(){}

What is destination of identifier G ?

Is there any other reason to name it other than use it for recursion?

Is there a way that I could access identifier G ?

Answer 1

The name of functions is shown in the stack trace, if there is an exception thrown.

The name will typically also be shown in the debugger's scope window:

For these two reasons, naming anonymous functions can make debugging easier, especially when dealing with complex call structures with many anonymous functions.

If for some reason, you want to access the name of the function, you can do so with F.name
