Can JavaScript Handle Large Scale Enterprise Applications?

According to the latest usage statistics posted on W3schools.com, over 91% of all websites use JavaScript coding as a client-side programming language. There are also a number of programmers who prefer writing both client-side and server-side code in JavaScript. However, the developers have to rely on frameworks like Node.js to use JavaScript for server-side development. JavaScript can effectively handle large-scale and complex enterprise applications.

Why JavaScript can handle Complex Enterprise Applications Effectively?

Simplify Composition of Complex Enterprise Applications

The programmers can easily speedup development of a complex enterprise application by simplifying its composition. JavaScript libraries make it easier for programmers to simplify the composition of complex business applications by creating shadow DOM boundaries. The Shadow DOM make web browsers to generate and deliver documents using common HTML tags like div, select and input. In addition to decoupling the components of individual JavaScript frameworks, the shadow DOM will further facilitate seamless communication between the components. Thus, JavaScript will help programmers to maintain and manage effectively by simplifying their composition.

Responsive Web Design

Many surveys have highlighted that a large percentage of people nowadays access websites on their mobile devices. Likewise, a gradual increase is being noted in the number of organizations implementing bring your own device (BYOD) policies. So the businesses need to ensure that the enterprise application delivers quality user experience across different devices. As a modern website design technique, responsive web design helps businesses to make their web-based enterprise deliver quality user experience across a variety of devices. But responsive web design emphasizes on usage of open technologies like HTML5, JavaScript and CSS3.

Isomorphic  Application  Development

Many businesses nowadays opt for isomorphic JavaScript development to create web applications that deliver richer user experience across many devices. The programmers also find it easier to manage, update and maintain the isomorphic JavaScript applications. The development model requires programmers to write both client-side and server-side code in JavaScript. As the entire code base is developed using a single programming language, it becomes easier for developers to manage and update without putting any extra time and effort.

Transpilers to Simplify JavaScript Programming

JavaScript was originally designed as a client-side scripting language of web browsers. So it lacks some of the advanced features provided by modern programming languages like Java or C#. But the developers still have option to use a number of transpilers to simplify JavaScript programming. The users also have option to choose from a number of transpilers including CoffeeScript, TypeScript, DukeScript and Vaadin. These tools make it easier for programmers to add functionality to the enterprise application by making the workflow complex. These transpilers further make JavaScript effective in handling a variety of modern enterprise applications.

Availability of Many JavaScript Frameworks

Some of these JavaScript frameworks are robust and fully-featured, whereas others are simple. The programmers can use large frameworks like Angular and Ember to add functionality to the enterprise application rapidly. At the same time, they also have option to use lightweight libraries like React to accomplish a specific task efficiently. Also, they can use specialized tools like Node.js to use JavaScript as a server-side programming language. At the same time, they can avail tools like NPM to install and manage the JavaScript libraries used by the enterprise application smoothly and effectively.

On the whole, a business has option to use JavaScript for developing both frontend and backend of the enterprise applications. It can further curtail the development time and cost significantly by deploying full-stack developers to write both client-side and server-side code in JavaScript. However, the programmers will need a variety of JavaScript libraries, tools and frameworks to create more efficiently.

How Good Is JavaScript coding for Building a Large Scale Web Application?

According to the most recent statistics posted on w3techs.com, more than 89% of websites currently use JavaScript as a client-side programming language. As a cross-platform and lightweight programming language, JavaScript coding makes it easier for programmers to build responsive websites and web applications that work with seamlessly with popular web browsers, operating systems and devices. It is also widely used by programmers as part of the web browsers to accomplish important tasks like browser control, user interaction, and asynchronous communication.

Also, the programmers have option to use JavaScript as a server-side scripting language through Node.js and similar runtime environment. At the same time, they also can use a variety of open source frameworks to reduce the amount of time and effort required for building JavaScript applications. It can also be used along with HTML5 and CSS for creating web applications and games. So you can always consider using JavaScript as a dynamic client-side programming language for building large scale web applications.

Advantages of Using JavaScript for Large Scale Web Application Development

Supported by Major Web Browsers

JavaScript is supported by most of the widely used web browsers including Firefox, Chrome, Internet Explorer, Safari and Opera. It is also supported by the new web browsers whose vendors have implemented JavaScript. So the users can access the web applications using JavaScript regardless of their choice of web browser. They also have option to access all functionality of the website by enabling the scripting language if it is disable due to some reason.

No Need to Use Any Specific Tools

JavaScript is an interpreted programming language. So you can easily write the code without using any specific tool or program. You can simply open a notepad, and start writing JavaScript code. Also, you have option to use a number of editors to identify the mistakes in the code. The editors colorize or reformat the script to make it easier for users to identify the errors.

Option to Reuse the Code

You can further reuse the JavaScript code across multiple pages simply by placing the code in separate files. After placing the code in a separate file, you have to save the file with.js extension. The file can be linked to multiple web pages by using the <script> tag to the HTML code of the page. The option enables you to avoid writing additional code while adding the same functionality to various parts of the website.

Many Libraries and Frameworks

You have option to reduce the time and effort required for building large JavaScript applications by using several frameworks and libraries. Many programmers prefer using dynamic JavaScript frameworks like AngularJS, Backbone, Ember and React. However, you still have option to choose from a long list of JavaScript libraries according to your specific needs. For instance, you can effectuate GUI development using widgets like DHTMLX, Bootstrap, jQuery UI, DojoWidgets or AngularJS. Likewise, you use popular template systems like jQuery Mobile, Handlebars, Mustache and Cascade Framework.

Comparatively Faster

As noted earlier, JavaScript is a client-side scripting language. So the code is executed on user's system. As the code is executed without any server interaction, the processing is done at a comparatively faster. The faster processing enables the web application to keep the users engaged by delivering richer browsing experience.

Deliver Updated Response Data from the Server

JavaScript further uses the Xml Http Request API for data retrieval. The API sends HTTP or HTTPS requests to the web server, and load the response sent by the server in the script. The script can easily update the current web page based on the response data received from the server without reloading a new web page. So you can boost the web application's performance by providing updated information to the users without reloading the web page completely.

Javascript Error - Different Types of Javascript Errors and How to Fix Them

Getting JavaScript coding error messages while surfing the web can be annoying because you experience freezes and crashes which cause disturbances to your peaceful web surfing. So why do we get errors in the first place? JavaScript is what makes up a website so when we get JavaScript errors it may be a problem with the JavaScript codes in a certain web page.

So there are two types of JavaScript errors that you have to be familiar with:

o Syntax error- means there is a typo or perhaps a character missing in the code which is why the error occurred. This error appears while the page is loading

o Runtime error- this occurs when a specified object is not found or when the script is not able to complete the instructions. This error appears when the affected code is running.
The error message appears in the form of a small icon which you can click to further check the error message. So how do you fix the JavaScript error?

1. The problem maybe with your browser because different browsers also react differently with each website that you visit so try switching to a different internet browser.

2. If that does not work check if the Java installation is working by visiting the java website java.com to do the test. Look for the dancing duke. If you are able to see it then it is working fine.

3. If you did not see the dancing duke that means that the Java installation is not working. For Internet Explorer users, enable your Java by going to Tools, Internet Options, go to the Security tab, click Custom Level and look for the Scripting of Java applets, click enable and then click OK. For Firefox users, you can enable Java by also going to Tools, Options, the Content tab and then check Enable Java.

4. Getting the latest updated version may also solve the error messages.

5. Also try to clear the temporary files or delete the cookies. You can do this in Internet Explorer by going to Tools, Internet Options, on the General tab, you will see the Delete Files and Delete Cookies. For Firefox users, go to Tools and Clear Private Data.

6. The last solution would be to uninstall Java and then install it again.

So these are the steps that you can do to fix and take care of those errors. Actually the JavaScript errors are also helpful in some way that it shows you that something maybe also wrong with the website. Though sometimes annoying it can also be a little helpful in some way.

Differences between JQuery and JavaScript

As a hugely popular client-side scripting language, JavaScript does not need any introduction. In addition to being used as part of web browsers, JavaScript also controls the web browsers, effectuates user interaction, facilitates asynchronous communication, and delivers customized content to users. So most web developers use JavaScript coding to reduce the time and effort required for building large or complex websites. The web developers also have option to use several JavaScript frameworks to effectuate and speedup web development.

JQuery is a widely used cross-platform JavaScript library. Despite being open source, jQuery is easy to use, fast and concise. The API provide by jQuery works seamlessly on major web browsers. Also, the feature-rich JavaScript library makes it easier for web developers to manipulate HTML documents, handle events, create animations, select DOM elements, and build AJAX application. At the same time, jQuery can also be used for creating a variety of plug-ins by taking advantages of the JavaScript library.

 

Thus, the modern web developers have option to use JavaScript and jQuery either independently or side by side. However, it is also important for the programmers to understand some of the major differences between JavaScript and jQuery.

4 Important Differences between JavaScript and jQuery

1) Programming Language and Library

As a dynamic programming language, JavaScript supports object-oriented, structured, functional and imperative programming styles. The first-class functions and dynamic typing also make JavaScript categorized as a prototype-based scripting language. On the other hand, jQuery is a JavaScript library. The framework makes it easier for developers to accomplish a number of common web tasks like HTML document manipulation, event handling, animation, DOM element selection and AJAX application development.

2) Scripting Time

When a web developer decides to use straight JavaScript, he has to write additional code to accomplish several tasks. He further has to put extra time and effort for debugging and fixing browser compatibility issues. But jQuery allows developers to take advantage of existing scripting. So they can use the scripting existing in jQuery to accomplish a number of web tasks without writing longer lines of code. Thus, jQuery makes it easier for web programmers to save the time and efforts required for building modern websites and internet applications.

3) Simplification of Client-Side Scripting

As a client-side scripting language, JavaScript makes it easier for developers to effectuate user interaction and deliver customized content to users. But the developers have to write longer lines of code to write a web application in straight JavaScript. So web developers often use JavaScript development frameworks to accomplish the scripting functions easily and quickly. As a cross-platform JavaScript library, jQuery comes with features to perform the common scripting functionalities. So developers can use the library to simplify the client-side scripting of HTML. The plug-ins, widgets and UIs provided by the framework help web programmers to drastically reduce development time.

4) Performance

Both JavaScript and jQuery run quite faster on the latest web browsers and computers. But the speed of both JavaScript and jQuery is impacted by use of older web browsers. As JavaScript can access the DOM faster than jQuery, the programmers can easily curtail the overheads associated with the library. However, jQuery makes it easier for developers to build high-performing websites and internet application by availing functionality independent of web browsers.

On the whole, JavaScript is a dynamic and feature-rich programming language, whereas jQuery is a library of JavaScript code. The proficient JavaScript developers can easily use jQuery to accomplish a variety of tasks without writing longer lines of code. However, they can still use jQuery without being proficient in the popular client-side scripting language. That is why; the developers need to choose JavaScript or jQuery according to specific needs of the project.
