Use of fetch API inside javascript expression

Q&A
1

Hi,

Im trying to assign  to a variable of type json a response that comes from a fetch API array in a javascript expression.

Right now my javascript code looks like this:

if($data.usuarios && $data.usuarios.length){
    // generate an array of url
    const urlUsuarios = $data.usuarios.map(usr => `../API/identity/user/${usr.user_id}`);

    // create an array of fetch
    const fetchPromises = urlUsuarios.map(url => fetch(url).then(resp => resp.json()));

    // execute all request
    Promise.all(fetchPromises).then(resps => {
        console.log(resps); // this print the array of users

        $data.posiblesUsuariosVar = resps; // this is assigment is not working
    });
}

Aother question that I have is if its posible to use async await syntax inside of a javascript expression

Thanks,
