A dynamically type safe, robust and flexible function name retrieve.
###usage
var funcname= require( 'func-name' );
var namedFunc = function this_is_my_name(){};
var anonymusFunc = () => {};
console.log( funcname(namedFunc) );
// this_is_my_name
console.log( funcname(anonymusFunc) );
// an empty string literal as a logical false
// you can change the name returned for an anonymus function
funcname.anonymusName= ':(';
// or call nameAnonymus on funcname to set it, restricted to string type
funcname= require( 'func-name' ).nameAnonymus( '?' );
console.log( funcname(anonymusFunc) );
// ?
// or without argument to default to 'anonymus'
funcname= require( 'func-name' ).nameAnonymus();
console.log( funcname(anonymusFunc) );
// anonymus
// for debugging you can enable error log on passing a non-function argument
funcname.debug()
// or pass your own debug helper/handler
funcname.debug( (err) => {
// do something with err
