how to get a array for a promise

Question

now I get a promise object,but I don't know to get the PromiseValue from that promise. The structure is following that

Promise {[[PromiseStatus]]: "pending", [[PromiseValue]]: undefined}
        [[PromiseValue]]:Array(63)

You should use:

Promise.all([array where each element is a Promise])

Promise.all returns a single promise. Depending on the implementation, the response is an array containing the response from each Promise in sequence. If any of the Promise rejects, Promise.all rejects with the rejected value.

I need the result as the style of array or object ,rather than return promise object – yolanda Apr 06 '17 at 02:16

how about using `.then` and `.catch` as so `Promise.then(function(your_wanted_value_is_here) {} ).catch()` – Quan Vuong Apr 06 '17 at 02:59
