Hello guys,
It strikes me as an interesting development to see that the current
definition of Async/Await (as I see it), is as simple syntactic sugar for
.then(). While I, to an extent, see the point of such a command as being
useful, I remain unaware of the exact reasoning why we need to include
promises in the first place. Wouldn't it be so much more powerful to be
able to use completely normal syntax, as you would in synchronous code,
instead of the awkwardness of Promises?
For example, take the following code snippet:
function asyncFunction() {
return new Promise((resolve, reject) => {
someAsync('data', (err, data) => {
if (err) {
reject(err); return;
}
resolve(data);
});
});
}
This seems to be so very confusing for anybody new studying this language,
almost everyone I talk to gets stuck up on some part of it. Wouldn't it be
so very beautiful if we could just do:
function asyncFunction() {
someAsync('data', (err, data) => {
return [err, data]
})
}
When we call this with the `await` keyword, we simply `await` a return. No
special promises or extra keywords needed, everything works as you would
expect it to.
async function asyncFunction() {
let [err, data] = await asyncFunction()
}
Honestly, are we just making life complicated for ourselves with utilising
promises & await/async?
