Non-JavaScript Functions

Almost every popular function in other programming languages can be interpreted in JavaScript. Pure JavaScript applications online can provide the experience that can rival popular online applications. With the use of frameworks and select libraries, JavaScript and Ajax based applications can be developed with ease.

But just because every function can be used with JavaScript, a developer doesn’t have to force their online application with JavaScript functions. Some functions in an online application are better off using other programming languages. In fact, some developers recommend that if there's a function that can be done without using JavaScript, the non-JavaScript option should be considered.

The reason for moving away from JavaScript is on performance on the client side. Of course, JavaScript can perfectly work in ideal conditions but not everyone can access the online application in this condition. By combining JavaScript with other programming languages, the application becomes lighter which increases speed of implementation.

The following are functions that are ideally better when used with non-JavaScript function:

• Loading Content

Interaction is one of the best features of JavaScript. But being interactive doesn't mean openness to a lot of content. When Ajax allows users content, almost everything can be done in the online application. Even attacks that crawls the entire application for additional information can be done with content loading. Using a non-JavaScript standardizes connection and anything out of the ordinary is flagged.

• Validation

There are two reasons why validation with the use of JavaScript could be a bad idea: first client side loading every data for validation could take time. Second, validation in the client side can be easily manipulated. The source code could be easily read which means attacks customized for the application can be created.

• Styling in Online Applications

JavaScript is always associated with efficient data manipulation. The programming language was never intended to create flashy websites since the functions in JavaScript that provide styles can easily drag the application. There are better programming languages that can work well with JavaScript and can provide additional features to the application.

Pushing for More CSS

Aside from relying in JavaScript to stream data in the client side, it's also a better idea to use CSS in providing information to users. CSS uses the server in connecting the data to customers and can be manipulated by JavaScript. This increases security while maintaining interaction with users.

Pushing for More Server-Side Function

The biggest challenge every developer has to address when using JavaScript to build online application is security. The client side can't be simply encrypted as developers also access the client side to make the necessary changes. Users also need the client side to be lenient so that data can be provided faster. But this leniency can also open the possibilities for attacks.

For that reason, every sensitive information when developing an Ajax based application should be used with server side programming languages. This increases security while providing enough interaction with what the users wanted and customization that developers wanted in an online application.
