await在if else语句中执行顺序问题

Question

      const promiseFn = () => {
        return new Promise((resolve, reject) => {
          setTimeout(() => {
            resolve(100);
          }, 2000);
        });
      };
      const foo = async () => {
        let x = "";
        if (x) {
          console.log("2");
        } else {
          const data = await promiseFn();
          x = data;
          console.log("3");
        }
        console.log("4");

        const user = {
          userId: x,
        };
      };
      foo();

打印结果为3，4。 问题为：await是异步的，为何打印结果不是4，3？

Answer 1

await 会暂停当前函数执行，直到 promise resolve 。
