Script Preparation code:

var sync = i => document.body.attributes[0]?.name + i;
var a_sync = async i => {await Promise.resolve(); return document.body.attributes[0]?.name + i;}
var syncAnon = function syncAnon(i){return document.body.attributes[0]?.name + i;}

Tests:

sync
for (let i = 0; i < 100; i++) sync(i);
async
for (let i = 0; i < 100; i++) a_sync(i);
syncAnon
for (let i = 0; i < 100; i++) syncAnon(i);
