Benchmark: Adding fields to functions

Script Preparation code:

function unmangle(s) {
  return s.replace(/\$\d+$/, "").replace("$_", "-");
}

Tests:

fun-assign
var f; var sum = 0; for(var i = 0; i <= 100000; i += 1) { f = function(j) { return j; }; f.name = "fun-name"; sum += f(i); } console.log(unmangle(f.name));
no-assign-named
var f; var sum = 0; for(var i = 0; i <= 100000; i += 1) { f = function fun$_name$2(j) { return j; }; sum += f(i); } console.log(unmangle(f.name));
object-assign
var f; var sum = 0; var o = {}; for(var i = 0; i <= 100000; i += 1) { f = function f(j) { return j; }; o.name = "un$_name$3"; sum += f(i); } console.log(unmangle(f.name + o.name));
define-prop
var f; var sum = 0; for(var i = 0; i <= 100000; i += 1) { f = function(j) { return j; }; Object.defineProperty(f, 'name', {value: 'fun-name'}); sum += f(i); } console.log(f.name);
fun-assign mangled
var f; var sum = 0; for(var i = 0; i <= 100000; i += 1) { f = function(j) { return j; }; f.name = "fun$_name$1"; sum += f(i); } console.log(unmangle(f.name));
