MochiKit Framework

Developing Ajax or JavaScript based application is currently done mostly with frameworks. Although there are developers who can create highly interactive applications without the assistance of frameworks, the existence of these tools has allowed developers to create applications faster. The ability to handle massive data and commands were already tested before the framework is released. For that reason, practicality will suggest that it's better to create an application with a framework. Manual coding is still a noble task but there are too many bugs that could encountered.

One of those frameworks that can assist developers to easily create an Ajax based application is MochiKit. This amazing framework was developed by Bob Ippolito and continues to be supported by many developers worldwide. It's a unique form of framework because of its ability to be compatible with future iterations of JavaScript unless the programming language is completely revised. By focusing on features, the framework should be able to adapt to manual coding of JavaScript and other frameworks.

Smart Use of DOM

The most impressive feature of the framework is on how it works with DOM. MochaKit comes with DOM Coercion Rules which is an automatic function integrated in every application. As the name suggests, this type of mechanism will allow developers to create DOM functions with constant scrutiny from the framework. This feature is even complemented with a set of tools that will allow developers easily create DOM functions. The framework will basically allow developers to create DOM functions that can be fully compatible and optimized.

Simplified Event Handling

The traditional event handling feature in JavaScript is already convenient for many developers and MochaKit didn't change this method. After all, changing something that's already working can only lead to confusion. The event handling function uses the command "connect" in order to call a function and related data. Developers can simply identify the functions needed through "user_id" function.

Those familiar with various frameworks will immediately recognize this technique on other frameworks. However, it should be emphasized that the "user_id" should be accurately placed in event handling so that the application will be properly rendered.

Challenges to MochaKit

Although MochaKit is an impressive application, there are some things that every developer should remember when adopting this framework:

• Lack of formal support - it's already an established fact that MochaKit can work with various future iterations of JavaScript. However, the lack of formal support will always place developers in limbo whether their current framework will work with the latest update of JavaScript and other libraries.

• No widget support - it's quite surprising that MochaKit do not come with full widget support. MochaKit can aid developers build an application but they are unable to integrate some of their functions in other uses. However, the application is still light and can be used in various purposes.

• Limited support for Opera browser - MochaKit can work in various browsers except for Opera. For some reason, some of its functions cannot be interpreted by Opera's JavaScript engine.

Overall, MochaKit is an impressive application that can aid developers build lightweight yet interactive applications. If the developer is willing to gamble a bit on the lack of support, this framework is highly recommended.
