Object Constructors and Literals

Developers often extensively work with variables in order to develop a highly interactive application. While this might not happen in some JavaScript and Ajax based applications, variables often provide the needed set of rules on how data interacts with functions.  Developers who are able to harness the power of variables should expect an application that easily interacts with users.

Of course, everything is not dependent on variables but developers should still work with variables to ensure the application works as expected. But variables in itself are simply tags or a name of a function in the application. Developers still have to implement certain functions so that variables will be properly implemented.

Using Object Constructors

The most popular practice when working with variables is to use object constructors. In gist object constructors will allow developers to practically do everything with the variable. Object constructors will also allow developers to prepare the variables to their preferred function.

Some of the object constructors are array(), float(), str() and int(). These constructors manipulate the variables by adding data or specify the variables behavior. It is a very straightforward pattern in JavaScript so it is relatively easy to implement.

Working with Literals

Although object constructors provide a smart solution in order to manipulate variables, there are some situations wherein another option should be explored. This does not mean constructors in itself are bad ideas in some functions. This simply means there are better options for developers to consider.

One of those scenarios is on regular expression. Object constructors can easily implement regular expression through this function RegEx(var). Without comparing this technique, object constructors will work as expected.

On the other hand, another option for regular expression should be considered. Developers can use literals in their Ajax and JavaScript based applications.

Literals or primitive data types is a more straightforward function in dealing with variables. With object constructors, developers will have to specify the behavior before anything will happen in the variable. But primitive data types use a much simpler technique in working with variables.

The main advantage of primitive data type of object constructors is the built-in support to various functions in JavaScript. Because the support is "native" to the functions in Ajax and JavaScript based applications, implementation should be faster.

Although it is not conventional, developers will be able to take advantage of the native support. This is most helpful in regular expressions. RegExp might require additional resource before implementation. Using object constructors will still work but compared to built-in capability of literals, developers should be able to implement RegExp faster.

Object constructors and literals have to be explored by developers in order to effectively build an Ajax based application. Object constructors are common and very popular because it works as expected.

On the other hand, there are other options developers can consider if they want their application to be fully optimized. A good example is to use literals instead of object constructors in Regular Expressions. It is a small aspect in the application but still has an impact on how the application interacts with users.
