JavaScript Why I get pending from this function 

async function test() {
    const res = await fetch('https://www.easy-mock.com/mock/5c6d317e8d040716434d0a5b/reading/category/homeSmallCategory');
    console.log(res) // data
    return res;
}
console.log(test()) // Promise {<pending>}

setTimeout(() => {
    console.log(test()) // Promise {<pending>}
})

Please parse it at the console.

How do I deal with this problem.I want the data processing in the test function .But it always return Promise {<pending>}. And then I think that I can deal with it like this.

if (res instanceof Promise) {
    res.then(data => res = data);
}

I put it at the end of the test.But it still not working.I console the Object.prototype.toString.call(res).And then I get [object Array].I realized that inside the function. The res is an array not matter what.But at the outside the res is not alike that. I know this is something about event loop.Thanks for your help.
