Creating an AsyncQueue for guaranteed sequential execution of asynchronous functions

It is necessary to develop a class that will execute the passed functions strictly one after another, even if they return a Promise.

const asyncQueue = new AsyncQueue();

asyncQueue.add(() => console.log("1"));
asyncQueue.add(
    () =>
    new Promise((resolve) => {
        setTimeout(() => {
            console.log("2");
            resolve();
        }, 1000);
    })
);
asyncQueue.add(() => console.log("3"));
asyncQueue.add(
    () =>
    new Promise((resolve) => {
        setTimeout(() => {
            console.log("4");
            resolve();
        }, 500);
    })
);
