— I'm desperately missing a way for arrow functions to call themselves

—

So I came up with this:

const selfref = (f, ...args) =>

  f.call(this, (...args) =>

    selfref(f, ...args), ...args);

Usage:

selfref((self, a, b, c) => {
  self(a, b, c);
  // calls the current
  // function again
});

— Lol

— I just realized private symbol members can just be wrapped in functions

—

var mySym = Symbol();
function doThing(sym) {
  if (sym === mySym) {
    // Do something 
  }
}

— I did know this before but forgot to mention it last night

— Uhh

— Can be a query or command function I guess

— I see, to avoid exposing the object with the symbol as prop?

— Or?

— Right

— Did you look at this?
