Speeding Up Object Instantiation

Object instantiation is important for Ajax since it increases the loading time of its functions. Developers have to work with objects most of the time since the objects should be able to determine the behavior of the functions as well as its performance.

However, the number of objects in an Ajax application will never mean that the function will work faster. There are certain tricks that the developer could do to ensure that the objects will work for the optimization of the application instead of being a burden.

For simple Ajax applications, developers can treat each object individually when relating to the function. However, complex Ajax applications should never have the same object setting so that it could maintain its speed despite the heavy coding of the application.

Instead of treating the objects individually, developers should bounce the objects as one based on the functions of the application. Because heavy applications requires a lot of functions which also in turn requires even more objects, binding the objects as one will greatly reduce memory since objects will never be read individually.

However, binding the objects comes with a great price. Objects instantiation will not be optimized since each object can’t be easily looked up. When objects are bound as one, the application will have to take time before it can determine which object to use. Although loading is fast and memory is optimized the execution of function is slower.

There is actually a work around so that object instantiation could be optimized even when they are bound as a single object. Instead of separating the objects, developers removed some functions in Ajax. By removing some basic functions, object reading will be optimized because some functions will never exist to consume the client’s memory.

The first function that should go is the eval function. Eval is run through every object before they are actually executed. That means an extra step before the object becomes available to the user. The reason why developers are not at ease in letting this function go is basically on the security of the functions. But with or without eval, the application should still run and if the coder is careful in building the application.

Another function that should be “tweaked” by developers is the setTimeout and setInterval. These functions are more important when compared to eval so developers were only able to change the behavior of the function instead of removing them completely to optimize object instantiation. Instead of removing these functions, developers should instead tweak the function and point them into another function.

More often than not developers who build light application could just point the function to an error message. But instead of doing that, developers could point the function into another function instead of an error message.

In doing so, the objects will be optimized and the application will run smoothly. By removing eval and tweaking setTimeout and setInterval developers will have a highly optimized websites even though the objects are bound in a single function.
