    }

    async function test() {
      /* let result = fn2().then(value => {
      　　　　console.log(‘value‘,value)
      },
      reason => {
      　　console.log(‘reason‘,reason)
      });*/

        let result = await fn2();
        console.log(‘result‘, result)
      } catch (error) {
        console.log(‘error‘, error)
