resolve(1)
}, 2000);
});
p1.then(function (val) {
console.log(val,'resolved 1');
var p2 = new Promise(function (resolve, reject) {
console.log('start promise2');
// throw Error('My Error !')
global.setTimeout(function () {
reject(2)
}, 2000);
});
return p2;
},function(val){
console.log('rejected promise1')
}).then(function(val){
console.log(val,'resolved promise2')
return val;
},function(val){
console.log(val,'rejected promise2')
return false
}).then(function(val){
console.log(val,'passed arguments')
},function(val){
console.log(val)
});
var p2 = new Promise(function (resolve, reject) {
console.log('start promise2');
global.setTimeout(function () {
resolve(1000)
}, 1000);
});
var p3 = new Promise(function (resolve, reject) {
console.log('start promise3');
global.setTimeout(function () {
resolve(3000)
}, 3000);
});
Promise.race([p2,p3,function(){return 2}]).then(function(val){
console.log(val)
},function(val){
console.log(val)
})
Promise.all([p2,p3,function(){return 2}]).then(function(val){
console.log(val)
},function(val){
console.log(val)
})
