Transform recursive function to recursive arrow function

Question

I have the following code with a recursive function which I would like to transform to recursive arrow function:

const hasAccess = menuSections.some(function s(x) {
  if (x.link === route.routeConfig.path) {
    return true;
  }

  if (x.sections) {
    return (x.sections.some(s));
  }

  return false;
});

Any idea on how to do it?

Answer 1

You could use an own function for callback and shorten the conditions for the return value.

const 
    check = x => x.link === route.routeConfig.path || x.sections && x.sections.some(check),
    hasAccess = menuSections.some(check);
