Question

Normally, a function can access itself like this:

(function f() {
    console.log(f); // Prints the function definition
}());

However, when the function f has an argument also called f, the argument takes precedence:

(function f(f) {
    console.log(f); // Prints 1
}(1));

In the second example, how can I access the function when one of the arguments has the same name as the function?

[Also, where can I find the documentation saying that the argument should take precedence over the function name?]

Answer 1

You don’t. Just follow this simple rule

Don’t shadow (or redeclare in a more specific scope) any variable that you want to use.

Note: arguments.callee will work for this, but only in some implentations. And it’s actually being phased out and is likely to disappear completely in the future.
