Dojo.js and YUI
The class system of Dojo uses prototype inheritance and its child classes will be powerful just like parent classes. Another prominent advantage of using Dojo toolkit is that all properties and methods are customizable. Dojo features deferred for several years and they are used for simple and advanced AJAX operations. Dojo toolkit has pioneered several I/O handling methods outside of standard XML, HTTP Request.
Apart from all these above-mentioned traits, Dojo provides a mechanism for building profiles in which the building system is taken as an input. Dojo toolkit provides a local, client-side storage abstraction named Dojo storage and it allows web applications to store data on the client side. Dojo storage facility establishes the best method for persistently storing information when included in a web page.
Web developers find YUI extremely useful for building simple web pages to complex web applications. Most talked about feature of YUI is that it is free for all users and it is developed in the open on GitHub. Photo browser and basic sliders are few basic examples of User Interface Library. YUI has been in use since 2005 and it has evolved tremendously over the time, thanks to the far-sightedness of Yahoo engineers. The objective of YUI developers at Yahoo was to deliver the best next-generation presentation technologies with an initial focus on in-house web developers. It is a well-known fact that User Interface Library includes several core Cascading Style Sheets resources.
In 2009, Yahoo released YUI3, a modern version of rebuilt YUI to modernize the library.
YUI 3 is equipped with advanced functionalities like CSS selector driven engine and small seed file. It was announced in 2014 that active development of YUI by Yahoo would cease citing the proliferation of server-side solutions. YUI has six types of components and they are YUI core, utilities, UI controls, CSS components, and developer tools and build tools. Also, YUI global object contains language utilities, a script loader, and other baseline infrastructure.
DOM collection associated with YUI will be of immense help in DOM scripting tasks including Cascading Style Sheet style management functionality. Event utility feature in YUI helps developers with safe and easy access to browser events. YUI’s Data Source provides a common interface for other components to interact with different types of data. Element utility embedded in YUI provides a wrapper for HTML elements in the DOM and Get Utility supports asynchronous loading of data.
