What do you think the output to console.log will be?
new Promise(function(resolve, reject) {
return resolve("X")
}).then(function(result) {
console.log("A1 " + result); // 1
return new Promise((resolve, reject) => { // (*)
resolve("Z")
});
console.log("A2" + result)
}).then(function(result) {
console.log("C" + result); // 4
});
console.log("D")
Output:
D
A 1
C 2
What do you think the output to console.log will be?
function test() {
return new Promise(function (resolve, reject) {
return resolve("1")
})
}
async function test2() {
let r1 = await test();
console.log("r1", r1)
return r1
}
let r2 = test2()
console.log("r2", r2)
Output:
r2 Promise {<pending>}
[[Prototype]]: Promise
[[PromiseState]]: "fulfilled"
[[PromiseResult]]: "1"
r1 1
