Deep Nesting

Nesting in JavaScript is a very useful technique for developers in building an effective Ajax based application. Through nesting, developers could implement functions within the function of an application. This means, the options in interacting with the programming language becomes almost unlimited.

You can create different functions within another function and these functions could contain different data formats and implementation. By carefully placing the nesting functions in the application, it could provide a smooth interaction with users.

But simple functions inside another function are not the only capability of nesting. Developers could push the nesting further without limitations. For example, the main function of the application will be composed of series of options.

Instead of ending the functions there, developers could even add a series of functions in one of the functions. This could continue on and on as long as the developer wants to. Through deep nesting, developers will be able to develop a highly intricate application. If the developers would be able to carefully plan the deep nesting strategy, they will be able to provide a highly efficient application.

Challenge for Deep Nesting

Deep nesting, on the other hand, is very challenging to be properly implemented. Although it is common practice today to use frameworks to shortcut the development process, deep nesting requires manual coding since the functions are not limited. The connection of the functions almost becomes a tree since there are numerous functions within the function.

But deep nesting is not a sturdy tree. It will rely on every branch for efficient implementation. If one of the functions fails to perform, there is a big chance that the entire application will not work at all. This is very difficult for developers since a single function could be challenging to monitor.

No Other Way

Once an error in the application happens because of deep nesting, the only way of fixing the problem is to check the application manually. Although there are debugging tools that could monitor the general behavior of the application, it will only take care of the general functions. The deep nested functions might be a little bit challenging to locate and could take sometime before it is located. This is especially true when the application is handed over to new developers.

For that reason, testing the application is always a must especially when functions are deep nested. It is better to find the problem early on rather than finding them later.

Keeping it Simple

Deep nesting may sound like an impressive technique in building an application but using this technique is not always recommended. If you want to create an application that could easily interact with users, then simpler application instead of an application with deep nested functions is highly recommended.

A deep nested function is only recommended if the developer knows the users not only in terms of preferred applications but also in hardware and software capacity. If the application is to be open for use, developers have to make sure that they provide the right hardware to support the application.
