App.Get('/Both', function(req, res) { let species = new Promise(function(resolve,

Question

App.Get('/Both', function(req, res) { let species = new Promise(function(resolve,

reject){
let data = await makeRequest(firstEndpoint);
if (data) {
resolve(data);
} else {
reject();
}
});
let planets = new Promise(function(resolve, reject){
let data = await makeRequest(secondEndpoint);
if (data) {
resolve(data);
} else {
reject();
}
})
Promise.all([species, planets])
.then(function(data) {
console.log('data', data);
res.send(data);
})
.catch(function(error) {
console.log('failed to resolve', error);
})
})

async function makeRequest(endpoint, resolve, reject) {
xhr.open(method, baseURL + endpoint, true);
xhr.send();
xhr.onerror = function() {
console.log('connection error: ', xhr.status);
console.log('connection error: ', xhr.response);
}
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200) {
console.log('xhr.responseText: ', xhr.responseText);
return xhr.responseText;
} else {
reject();
}
}
}
Вот почему это не работает?

promise и async/await в одной функции?
