allcljs
(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);

It rejects with the reason of first promise that rejects. There is no implied ordering in the of the array of Promises given.

all-settledcljs
(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);

catchcljs
(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 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) });`

resolvecljs
(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

(e.g. a promise that resolves to a promise that resolves to something)
a single layer.
