js.Promise — clojure-interop/cljs-web-api 1.0.10

The Promise object represents the eventual completion (or failure) an asynchronous operation, and its resulting value.

all cljs

(all this iterable)

Method.

The Promise.all() method returns a single js.Promise that resolves all of the promises passed as an iterable have resolved or when iterable contains no promises. It rejects with the reason of first promise that rejects. There is no implied ordering in the of the array of Promises given. On some computers, they may be in parallel, or in some sense concurrently, while on others they be executed serially. For this reason, there must be no dependency any Promise on the order of execution of the Promises.

Promise.all(iterable);

all-settled cljs

(all-settled this iterable)

Method.

The Promise.allSettled() method returns a promise that resolves all of the given promises have either resolved or rejected, with array of objects that each describe the outcome of each promise.

promise.allSettled(iterable);

catch cljs

(catch this & args)

Method.

The catch() method returns a js.Promise and deals with rejected only. It behaves the same as calling `Promise.prototype.then(undefined, (in fact, calling obj.catch(onRejected) internally calls obj.then(undefined, This means that you have to provide an onRejected function even you want to fall back to an undefined result value - for example => {}).

`p.catch(onRejected);

p.catch(function(reason) { // rejection });`

finally cljs

(finally this & args)

Method.

The finally() method returns a js.Promise. When the promise settled, i.e either fulfilled or rejected, the specified callback is executed. This provides a way for code to be run whether the was fulfilled successfully or rejected once the Promise has been with.

`p.finally(onFinally);

p.finally(function() { // settled (fulfilled or rejected) });`

length cljs

(length this)

Property.

Length property whose value is always 1 (number of constructor

prototype cljs

(prototype this)

Property.

The Promise.prototype property represents the prototype for the constructor.

race cljs

(race this iterable)

Method.

The Promise.race() method returns a promise that fulfills or as soon as one of the promises in an iterable fulfills or rejects, the value or reason from that promise.

Promise.race(iterable);

reject cljs

(reject this reason)

Method.

The Promise.reject() method returns a Promise object that is with a given reason.

Promise.reject(reason);

resolve cljs

(resolve this value)

Method.

The Promise.resolve() method returns a js.Promise object that resolved with a given value. If the value is a promise, that is returned; if the value is a thenable (i.e. has a `"then" the returned promise will "follow" that thenable, adopting eventual state; otherwise the returned promise will be fulfilled the value. This function flattens nested layers of promise-like (e.g. a promise that resolves to a promise that resolves to something) a single layer.

Promise.resolve(value);

set-length! cljs

(set-length! this val)

Property.

Length property whose value is always 1 (number of constructor

set-prototype! cljs

(set-prototype! this val)

Property.

The Promise.prototype property represents the prototype for the constructor.

then cljs

(then this & args)

Method.

The then() method returns a js.Promise. It takes up to two callback functions for the success and failure cases of the Promise.

`p.then(onFulfilled[, onRejected]);

p.then(value => { // fulfillment }, reason => { // rejection });`
