Double Checking JavaScript Code

The adoption of JavaScript and Ajax in websites is increasing in a very rapid rate. Almost every developer wants to learn about this programming language so that Ajax could be easily integrated in every online application they create. The beauty of the client side without any requirements from the user’s end is very appealing as it provides online interaction without any problem for the user.

Although there are still challenges in security for Ajax and JavaScript applications, the usability as well as aesthetic value of using JavaScript is clearly there. Because of the increasing familiarity of JavaScript, developing an application based on the said programming language is a lot easier today.

Error Tolerance

Aside from the increasing familiarity of developers with JavaScript and Ajax, an often ignored feature of JavaScript is also the reason why developing an application is now easier. JavaScript has a high error tolerance which means the functions that only resemble the standard coding in JavaScript could still be interpreted and even implemented.

If the missing code would just be in a single character, such as a semi-colon, the application will still push through. Developers would still expect an output from the application although it will slow down the application a little bit.

Repercussion

But this error tolerance should never be seen as an advantage for developers. In fact, it should be seen as a problem for many developers. Instead of highlighting the problem in your application, JavaScript will just ignore it and push the function without any problem.

At first glance, you will see that the application works well even with a “sloppy” coding. But the application will eventually slow down to a halt if you are trying to upgrade the application. You will see the difference when you start adding plug-ins to the application especially when they interact with the said function.

Minification

So far, the biggest reason why you need to double check your coding is minification. Minification is a process of shrinking your JavaScript and Ajax based application so that it could be easily read by browsers. This is often implemented in larger applications in order to improve accessibility even for low-end gadgets.

If there are errors in coding, the minified version of the application will never be able to convert the function. Naturally, your application will not work as expected. Instead of enjoying the advantage of error toleration of JavaScript, this feature has worked against you and your application.

Using Error Checking

On the other hand, checking your code manually could be very difficult not to mention time consuming. For that reason, it is highly recommended to have an error checker for your application. There are a good number of developing tools for JavaScript that you can use online for free.

Take your time to double check the coding in this programming language. Although JavaScript would be able to launch the functions even with few errors in coding, upgrading and minification of the application would be difficult if not impossible. JavaScript is still a complicated programming language that should be dealt with careful coding.
