问我可以使用TypeScript在同步函数中等待异步操作循环完成吗？

EN

const promises:Promise<{}>[] = [];
myWhatever.forEach(
    item => {
         const promise = new Promise<{}>(
             (resolve, reject) => {
                 // Do something which ends up with resolve getting called
                 // at some point
             }
         );
         promises.push(promise);
    }
);
Promise.all(promises)
   .then(
      () => {
          // Perform your post render tasks here
      }
    );

const promises = myWhatever.map(
    item =>
        new Promise<{}>(
             (resolve, reject) => {
                 // Do something which ends up with resolve getting called
                 // at some point
             }
        )
);
Promise.all(promises)
   .then(
      () => {
          // Perform your post render tasks here
      }
    );
