javascript定时器、promise、console执行顺序

  /*promise 、setTimeout(定时器) 、console.log*/

  setTimeout(function(){

console.log('setTimeout---');

  },0);

  var promise = new Promise(function(resolve, reject){

      console.log(\'promise---1\');

  resolve();

  console.log(\'promise---2\');

  reject();

  console.log(\'promise---3\');

  });

  console.log(1111);

  promise.then(function(){

console.log(\'promise---success\');

  }).catch(function(){

console.log(\'promise---fail\');

  });

  console.log(111555555551);

优先顺序

1、console == new promise 内的代码

2、new promise 下的resolve()或reject()

3、setTimeout
