2723. Add Two Promises
Description
Given two promises promise1
and promise2
, return a new promise. promise1
and promise2
will both resolve with a number. The returned promise should resolve with the sum of the two numbers.
Example 1:
Input: promise1 = new Promise(resolve => setTimeout(() => resolve(2), 20)), promise2 = new Promise(resolve => setTimeout(() => resolve(5), 60)) Output: 7 Explanation: The two input promises resolve with the values of 2 and 5 respectively. The returned promise should resolve with a value of 2 + 5 = 7. The time the returned promise resolves is not judged for this problem.
Example 2:
Input: promise1 = new Promise(resolve => setTimeout(() => resolve(10), 50)), promise2 = new Promise(resolve => setTimeout(() => resolve(-12), 30)) Output: -2 Explanation: The two input promises resolve with the values of 10 and -12 respectively. The returned promise should resolve with a value of 10 + -12 = -2.
Constraints:
promise1
andpromise2
are promises that resolve with a number
