Walking through the ups and downs of Javascript

JavaScript is a very prominent, light-weight, object-oriented, high-level, and dynamic and most widely used scripting language for web. It is said to be one of the three pillars of World Wide Web along with CSS and HTML. It is utilized in making interactive web content with online program which can consist of video games. It is open and cross-platform and interpreted rather than being compiled.

With such serviceability JS has some shortcomings also. Let us discuss in brief about both positive and negative aspect of JavaScript development services.

Advantages:

1. Easy to learn — Learning JavaScript is quite easy with syntax close to English making implementation simple yet flexible. It makes use of DOM model that offers many prewritten functionalities at developer’s dispose.

2. Browser compatibility — JavaScript is supported by most of the modern browsers available in the market today and has the capability to yield same output with no extra efforts needed.

3. Versatility — JavaScript is very versatile as it can be used in a broad spectrum of applications. You can place it in a web page having whichever file extension even inside a script written in different language like Perl or PHP.

4. Rapid execution Being executed on client-side, it reduces load and bandwidth from the server and makes execution fast for example you can validate the input before sending it over to the server. With no server interaction, the task can be completed almost instantaneously to get desired output.

5. Cross-platform — Besides browser JavaScript can be utilized for developing dashboards, Articulate, PDF editors, Photoshop, Dreamweaver and even a few embedded systems making it truly cross-platform.

6. Easy code sharing — As it is a high level language, issues like memory utilization and segment faults can be catered by itself without any intervention from your side. In addition, scripts and program can be effortlessly shared and run.

7. Rapid development — With easy and simple syntax development is involuntarily simple. Availability of third party add-ons also contributes in making the development cycle fast.

Disadvantages:

1. Security — JavaScript can be easily exploited and thus Security is considered a point of concern for Javascript as once a snippet is inserted in the web page it executes on the client side producing instantaneous output and making it vulnerable to malicious purposes.

2. Standard Support — As JavaScript has no standard support available across browsers DOM, different browsers give different access to objects.

3. Code Visibility — As code is at all times visible to everyone and anyone can play with it risking security.

4. Limited Capabilities No multiprocessor or multi threading capabilities available with JavaScript. Additionally reading from a file and writing to a file is also not achievable.

5. Varied Rendering — JavaScript may be rendered by different engines in different ways causing inconsistent functioning. Moreover JavaScript can be disabled from the browser hindering the rendering process for the page.

6. No render — Even with single error, whole website can stop render making it crucial to use JavaScript error tolerant browser.

The coin always has two faces and so is the case with any programming language. Whether you hire JavaScript consulting services or you are a developer yourself, the nature of your project entirely affects your choice of programming language.
