I had code below from javascript.info async/await tutorial and I noticed it has used new Promise next to await, this is the cut from the code:

await new Promise((resolve, reject) => setTimeout(resolve, 3000));
img.remove();

link to code

so it’s possible to type this code as below:

 await setTimeout(()=>{img.remove()}, 3000));

so I’m wondering what’s the necessity to use new Promise next to await keyword(while we eliminate .then() and .catch() with await and try...catch but I’ve seen new Promises get used alongside the await)?

p.n: I thought maybe it gets used when we have conditions for rejection and success inside new Promise but in this example we have no condition and still it’s used.
