The reason I’m getting obsessed with JavaScript

Standard

The main reason that I’m taking JavaScript seriously is that I got inspired by the rapid adoption of JavaScript and the related evolved vibrant frameworks built on top of it, in addition to that, the attraction and support JavaScript is getting from both the open source community and the majority of cooperate software companies a like.

I was amused by the language and its features when I started learning and experimenting with Node.js networking platform that is based on JavaScript event loop concurrency model. I got hooked instantly on Node.js lean approach to develop scalable lightweight server applications and its use of Google V8 JavaScript Engine and adoption of JavaScript as the main programming language for the platform. Until recently JavaScript was only popular and always attached to client side environments and never thought to be leveraged by server platforms.

But the main pragmatic reason I choose JavaScript over other languages is the vibrant ecosystem and frameworks build on top of it. It appeals to me the fact that I can use one portable language that is platform independent and spans both the client and server platforms cohesively which does not require a mind shift to switch between two different languages which is the case with the current traditional web applications development (use a different native language on the server “i.e. C#, JAVA ..etc).

The JavaScript and related frameworks had been always the de facto portable programming language and platform running on client side. But the JavaScript users took an innovative leap steps recently to be adopt and leverage it beyond the browser support and use it as a viable option to develop applications that can run on a server platform (in the case of Node.js); and also to develop native applications that run outside of the browser (for example in the case of Windows 8 applications). Microsoft also supports JavaScript language to write Map/Reduce jobs that run on Windows Azure HDInsight Service which is an implementation of Apache Hadoop running on Azure.

Netscape the company that invented JavaScript worked with ECMA International to standardized the language under the name ECMAScript. With the latest stable release of ECMAScript 5.0 standard and the rapid support by modern web browsers with the parallel evolution of HTML5 API, JavaScript becomes no longer a scripting language living in the web browser focusing only on dynamic interactions; it becomes a powerful tool to build modern web applications and be part of a vibrant ecosystem and platform that empower both the client and server environments seemingly. it makes the programming experience a more cohesive and consistent process.

I believe JavaScript has a promising future and it is happening now already and for that I got inspired to learn it and experience its capabilities and the mechanics of its vibrant ecosystem.

My core experience in the last years has been in .NET platform and C# language, I also used VBScript, VB.NET, C++ and even FORTRAN and Pascal in collage but something about JavaScript dynamic nature and portability is appealing. I can relate to it more than other languages though they can be more sophisticated and faster at runtime but I see it more relative to the real world and how it functions, its treatment of functions as first class citizens and its dynamic nature makes it closer to our brain functional model that depends on input/output to process and model data rather than objects abstractions through inheritance and hierarchical relationship as it the case in traditional object oriented programming languages.

The evolution of JavaScript is happening beyond the competition of major players in the software industry as it was born around the same time the internet was born so it becomes part of the web platform DNA and since then it continued to be implemented in each new generation of web browsers as a the default language regardless of the web browser brand or type. Its ECMAScript standards compliance assured portability and enforced consistency to some extent across all browsers and platforms, mutations may happen during its life-cycle of the language evolution but it always picked up by ECMA and everyone rush to catch up and support new emerged features. Its becoming a win win case for competitors to support it in their ecosystems and development platforms, it raises above their proprietary languages and technologies. And this by its own makes it a sustainable programming language that provides a safe heaven for programmers at least for the near future.
