我可以使用 java(type)script 异步实现 c# 任务吗？

Question

I'm just curious about doing asynchronous job with javascript or typescript .
I made some program with C# and following is source that I wrote.

static void Main(string[] args)
{
    var t1= Task.Run(() => { myFunc(0, ConsoleColor.Green); });
    var t2 = Task.Run(() => { myFunc(50000, ConsoleColor.Red); });

    t1.Wait();
    t2.Wait();
}

static void myFunc(int number, ConsoleColor color)
{

    for (int i = 0; i < 1e4; i++)
    {
        Console.ForegroundColor = color;
        Console.WriteLine(number + i);
    }
}

below is capture image of result.

I can imagine that why console does write above result.

and following source is written in typescript. I tried to simulate same result, but failed.

let i: number;
let j: string;
let k: number;
let mx: number =1e4;

function myFunc(offset: number, color: string) {

    return new Promise(() => {

        for (i = 0; i < mx; i++) {
            console.log(color, i + offset);
        }
    });

};

async function myFunc2() {
    const aa = myFunc(0, "\x1b[32m");
    const bb = myFunc(50000, "\x1b[35m");
    await aa;
    await bb;

}

myFunc2();

below image is typescript one.

can I get any advice for making same result with C# result in `java(type)script? I tried many times to implement, but many time I failed.
thank you for read.

JavaScript has only one thread in the same context, but the web browser APIs do not. We also have the possibility of simulating parallelism by using the setTimeout function or, with some limitations, by using the real parallelism provided by WebWorkers.
