ES6 字符串到 ReadableStream

Question

If I have a function which accepts a ReadableStream<string> , but I want to call it with a string argument, is the following the easiest/best way to handle it?

const stringToStream = str => new ReadableStream({
    start(controller){
        controller.enqueue(str);
        controller.close();
    }
});

readableStreamFunc(stringToStream("foo"))
