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.\n\n
Example 1:
\n\n\nInput: \npromise1 = new Promise(resolve => setTimeout(() => resolve(2), 20)), \npromise2 = new Promise(resolve => setTimeout(() => resolve(5), 60))\nOutput: 7\nExplanation: 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.\n\n\n
Example 2:
\n\n\nInput: \npromise1 = new Promise(resolve => setTimeout(() => resolve(10), 50)), \npromise2 = new Promise(resolve => setTimeout(() => resolve(-12), 30))\nOutput: -2\nExplanation: 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.\n\n\n

Constraints:
\n\npromise1 and promise2 are promises that resolve with a numberpromise1 和 promise2，返回一个新的 promise。promise1 和 promise2 都会被解析为一个数字。返回的 Promise 应该解析为这两个数字的和。\n\n\n
示例 1：
\n\n\n输入：\npromise1 = new Promise(resolve => setTimeout(() => resolve(2), 20)), \npromise2 = new Promise(resolve => setTimeout(() => resolve(5), 60))\n输出：7\n解释：两个输入的 Promise 分别解析为值 2 和 5。返回的 Promise 应该解析为 2 + 5 = 7。返回的 Promise 解析的时间不作为判断条件。\n\n\n
示例 2：
\n\n\n输入：\npromise1 = new Promise(resolve => setTimeout(() => resolve(10), 50)), \npromise2 = new Promise(resolve => setTimeout(() => resolve(-12), 30))\n输出：-2\n解释：两个输入的 Promise 分别解析为值 10 和 -12。返回的 Promise 应该解析为 10 + -12 = -2。\n\n\n
