Method Promise.resolve(value) mengembalikan objek {{jsxref("Promise.then")}} yang diselesaikan dengan nilai yang diberikan. jika nilainya thenable (mis. memiliki {{jsxref("Promise.then", "\"then\" method")}}), promise yang dikembalikan akan "mengikuti" thenable-nya, menggunakan keadaan ini; sebaliknya promise akan dikembalikan sesuai nilai yang terpenuhi.

Sintaks

Promise.resolve(value);
Promise.resolve(promise);
Promise.resolve(thenable);

Parameter

value
Argumen untuk diselesaikan oleh Promise. Dapat juga sebuah Promise atau thenable untuk diselesaikan.

Deskripsi

Fungsi statis Promise.resolve mengembalikan Promise yang terselesaikan.

Contoh

Penggunaan method static Promise.resolve

Promise.resolve("Success").then(function(value) {
  console.log(value); // "Success"
}, function(value) {
  // not called
});

Penyelesaian pada array

var p = Promise.resolve([1,2,3]);
p.then(function(v) {
  console.log(v[0]); // 1
});

Penyelesaian pada Promise lain

var original = Promise.resolve(true);
var cast = Promise.resolve(original);
cast.then(function(v) {
  console.log(v); // true
});

Penyelesaian thenables dan throwing Errors

// Resolving a thenable object
var p1 = Promise.resolve({
  then: function(onFulfill, onReject) { onFulfill("fulfilled!"); }
});
console.log(p1 instanceof Promise) // true, object casted to a Promise

p1.then(function(v) {
    console.log(v); // "fulfilled!"
  }, function(e) {
    // not called
});

// Thenable throws before callback
// Promise rejects
var thenable = { then: function(resolve) {
  throw new TypeError("Throwing");
  resolve("Resolving");
}};

var p2 = Promise.resolve(thenable);
p2.then(function(v) {
  // not called
}, function(e) {
  console.log(e); // TypeError: Throwing
});

// Thenable throws after callback
// Promise resolves
var thenable = { then: function(resolve) {
  resolve("Resolving");
  throw new TypeError("Throwing");
}};

var p3 = Promise.resolve(thenable);
p3.then(function(v) {
  console.log(v); // "Resolving"
}, function(e) {
  // not called
});
