JavaScript Error Types

JavaScript and Ajax are programming languages and techniques that are easily susceptible to errors. The complications in developing an Ajax based application; the security measures as well as data interpretation in the application could easily slow down the application or even halt its processes.

As a client side programming language, errors will naturally occur since users can freely interact with application and could use any form of data they wish.

Developers have to understand the common types of JavaScript errors. By understanding these errors they could build an application that could prevent or react to the said errors.

• Runtime Error

One of the common errors in JavaScript, runtime errors automatically informs the user that something is wrong with the application. When a runtime error happens, it means that the application cannot fully comprehend how data would interact with the online application.

The problem could be from the form of data submitted, the syntax that interprets the said data or both. When this happens, the application could still go through but the missing information could affect the final output of the application.

• Logic Error

Logic errors, unfortunately, should be pointed to developer’s inability to write the code correctly. These are commonly known as bugs and could present serious problems in the application. This is regarded as the “loophole” for the application wherein attacks could be implemented.

If this is not addressed as soon as possible, the susceptibility of the application will continue. Logic errors might even increase since the bugs will continue to interact with other functions – naturally creating additional errors.

• Loading Error

Probably the most challenging error a developer would face is the loading error type. When this occurs, the application would completely stop since the application will no longer continue to interact with the said command or data. This type of error happens in other programming languages as well but emphasis should be made on JavaScript and Ajax.

You have to remember that JavaScript is not just a simple client side programming language; its use in Ajax has increased its susceptibility to this type of error since it uses additional programming languages. If one of the programming languages will not work as expected, the application is not expected to work properly.

Syntax and Bugs

You may have noticed that the two most prominent source of problem are syntax and bugs. If the developer does not take care of the syntax by properly executing them, the application will most likely halt. On the other hand, bugs could only cause problems that could easily snowball if the developer does not take care of the problems as soon as possible.

These types of errors are considered a small chuck of the possible errors that could happen in a JavaScript and Ajax application. But these errors happen more than usual in many online applications. When these errors occur, swift action has to be taken since they present a big problem in the future not only for the application but also for the users.
