匿名异步函数调用

Question

Is it possible to create anonymous async function?

Of course named function works:

const test = async() => {
 await ... //fetch some data
}

But what is a working syntax for unnamed async function? Should we use IIFE here to call it?

Answer 1

 const test = async (asyncFunc) => { return await asyncFunc() } test(async () => { return "Hello World!" }).then(console.log)

Answer 2

async function() => {
   await ... 
}

Answer 3

two way,

1. simple way

!async function () {
    console.log("e",'yibu');
}();

or

(async  () => {
    console.log("e",'yibu');
})();

//maybe this is better then above
;(async function () {
    console.log("e",'yibu');
}());

//this is allmost same
;[ async function () {
    console.log("e",'yibu');
}()];

2. use [then] this is not absolute "anonymous"

var x=async  () => 100;

x().then(
    e=>console.log({e})
);
