Benchmark: reuse of audio elements in ratechangeTick with await

Tests:

reusing elements
(async function(){ var reusables = []; function nextTick(cb){ var resolve; var promise = new Promise(function (resolveImpl) { resolve = resolveImpl; }); var audio = reusables.length ? reusables.shift() : document.createElement("audio"); audio.onratechange = function(){ audio.onratechange = undefined; //todo not really necessary audio.playbackRate = 1; reusables.push(audio); resolve(cb()); } audio.playbackRate = 2; promise.cancel = function(){ audio.onratechange = undefined; resolve(false); return cb; } return promise; } var result = await nextTick(function(){}); })();
nonreusables
(async function(){ function nextTick(cb){ var resolve; var promise = new Promise(function (resolveImpl) { resolve = resolveImpl; }); var audio = document.createElement("audio"); audio.onratechange = function(){ resolve(cb()); } audio.playbackRate = 2; promise.cancel = function(){ audio.onratechange = undefined; resolve(false); return cb; } return promise; } var result = await nextTick(function(){}); })();
