我想创建类似处理同步行为和异步行为的东西。例如，我希望能够像这样：

function timeout(myJson) {
    return new Promise(function (resolve, reject) {
        setTimeout(resolve, myJson.wait, myJson);
    });
}

async function funct() {
    try {
        let PromiseTolaunch = [{ "wait": 10, "nextIndex": 2, "id": 1 }, 
                                { "wait": 500, "nextIndex": -1, "id": 2 }, 
                                { "wait": 5, "nextIndex": -1, "id": 3 }];
        let launchedPromise = [], finishedPromise;

        launchedPromise.push(timeout(PromiseTolaunch[0]));
        launchedPromise[0].id = PromiseTolaunch[0].id;
        launchedPromise.push(timeout(PromiseTolaunch[1]));
        launchedPromise[1].id = PromiseTolaunch[1].id;
        while (launchedPromise.length !== 0) {
            finishedPromise = await Promise.race(launchedPromise);
        [*] console.log(finishedPromise); // Expected output: { "wait": 10, "nextIndex": 2 …
