I am trying to use await-async without try-catch for this:
If you have such above single line async/await function, then this would have been clean code for you:
const getUsers = async (time, shouldReject=false) => {
return new Promise((resolve, reject) => {
setTimeout(() => {
if (shouldReject) {
reject(Error('Rejected...'));
} else {
resolve(["User1", "User2"]);
}
}, time);
});
}
const userOperation = users => {
console.log("Operating user", users);
}
// Example 1, pass
getUsers(100)
.then(users => userOperation(users))
.catch(e => console.log(e.message));
// Example 2, rejected
getUsers(100, true)
.then(users => userOperation(users))
.catch(e => console.log(e.message));
And for multiple await in a single async function, it would good to have try/catch block as below:
const users = async () => {
try {
const value = await getUsers(1000, false);
const value1 = await getUsers2(1000, false);
...
} catch (error) {
...
}
}
