Earlier versions of Dojo had a reputation for being bulky and slow to load. [13] It also required extra work to load Dojo across domains, e.g., from a CDN.Addressing these problems was the major goal of Dojo 1.7, which introduced asynchronous module definition (AMD) and a "nano" loader.
The asynchronous workflows are implemented as CE (computation expressions). They can be defined without specifying any special context (like async in C#). F# asynchronous workflows append a bang (!) to keywords to start asynchronous tasks. The following async function downloads data from an URL using an asynchronous workflow:
Asio is a freely available, open-source, cross-platform C++ library for network programming. It provides developers with a consistent asynchronous I/O model using a modern C++ approach. Boost.Asio was accepted into the Boost library on 30 December 2005 after a 20-day review. The library has been developed by Christopher M. Kohlhoff since 2003.
In C++11 a std::future provides a read-only view. The value is set directly by using a std::promise, or set to the result of a function call using std::packaged_task or std::async. In the Dojo Toolkit's Deferred API as of version 1.5, a consumer-only promise object represents a read-only view. [7]
The function that accepts a callback may be designed to store the callback so that it can be called back after returning which is known as asynchronous, non-blocking or deferred. Programming languages support callbacks in different ways such as function pointers, lambda expressions and blocks.
The engine currently includes the IonMonkey compiler and OdinMonkey optimization module, has previously included the TraceMonkey compiler (first JavaScript JIT) and JägerMonkey. JavaScriptCore: A JavaScript interpreter and JIT originally derived from KJS. It is used in the WebKit project and applications such as Safari. Also known as Nitro ...
MooTools also provides a detailed, coherent application programming interface (API), [10] as well as a custom downloads module allowing developers to download only the modules and dependencies they need for a particular app. [11] [12]
Alternatives are synchronous method invocation and future objects. [4] An example for an application that may make use of AMI is a web browser that needs to display a web page even before all images are loaded. Since method is a special case of procedure, asynchronous method invocation is a special case of asynchronous procedure call.
