How to call a specific function from inside a subfunction in javascript?

Question

How do I call function "a" from "av" without a direct reference "a()"

function a(){
    alert("1");
    this.v=function(){alert("hi")};
}

Answer 1

One way I can think of doing this without repeating a :

function a(){
    let indirect = arguments.callee;
    alert("1");
    indirect.v=function(){ indirect(); };
}

a();
a.v();

But this does not work under strict mode and you must call a before calling av .

You could also do:

function a(){
   alert('1');
   this.v = () => this();
}

a.v = a;
a.v();

This way you don't call a() and it also works under strict mode.

Answer 2

Set its v property outside the function itself:

 function a() { alert("1"); } av = function() { a() alert("hi") }; av()
