Patterns

$3

* Synchronous and asynchronous chain-of-responsibility. See examples in source/examples/behavioral/chain-of-responsibility

Utilities

$3

* success(callback, ...result) calls specified callback as successful with array of results
* fail(callback, error) calls specified callback as failed with specified error
* join(onSuccess, onError) builds classical callback function from two success-callback and error-callback
* wrapCallback(callback) builds callback function that wraps array of success results into single tuple
* unwrapCallback(callback) builds callback function that unwraps single tuple to an array of success results
* wrapWorker(worker) builds asynchronous worker function that wraps array of results into single tuple
* unwrapWorker(worker) builds asynchronous worker function that unwraps single result to an array of results
* collect(workersCollection) builds asynchronous worker that collects results from all passed workers
* guardAsyncProcessor(guard, processor) builds asynchronous processor responsible only for type-guarded context

$3

* guardPromiseProcessor(guard, processor) builds asynchronous processor responsible only for type-guarded context

$3

* class Unexpected Base class of unexpected context exception
* unexpected(message?, callback?, next?)` Calls next (if specified) or passes Unexpected exception to callback (if specified)
