7 Reasons Why JavaScript is useful for the Internet of Things

Internet of Things is one of the latest and most useful technologies in our world. It is a vast topic with a huge scope for innovation pertaining to advanced automation solutions in a variety of contexts. IoT, as it is commonly called, has applications in various projects, such as transportation, home automation, smart cities and more.

JavaScript for the Internet of Things

It consists of various hardware devices embedded with things like sensors and WIFI connectivity which allows devices to exchange date over Wifi with other embedded devices or smartphones. A lot of such embedded devices can also be remotely controlled through mobile applications on smartphones.

There are various technologies which facilitate the development of this technology. Talking about programming languages, we have C which is written directly on such embedded devices. But, another important language which has ample scope in IoT development is JavaScript. Why JavaScript? Well, there are a couple of important reasons for it. Obviously, there are some benefits of using JavaScript for the IoT which opens up a new career avenue for JavaScript developers. Alright, so let us take a close look at 7 such primary reasons for using JavaScript in the field of IoT development.

1) JavaScript and Node.JS

Node.js is a robust technology which makes server-side implementation of JavaScript possible. Moreover, its event-driven, asynchronous input-output (IO) model is quite suitable for developing and maintaining web applications which respond to each other in real-time, something which is beneficial for IoT applications as well. A range of companies are leveraging the power of Node.js to build a network of devices, sensors and smartphones which can be controlled and manipulated remotely. Several large-scale companies like Microsoft and Samsung have already embraced Node.js as a technology for their IoT development projects.

2) JavaScript is the solution

JavaScript is not only a viable option but an effective solution to several IoT projects. It is because of the fact that JavaScript is a robust scripting language which communicates with browsers. Moreover, with a Node.js server-side implementation, JavaScript can allow manipulating and controlling a range of devices through internet easily. Besides, JavaScript is an important front-end development technology for designing smart and intuitive user interfaces for various cross-platform web applications using HTML5. It allows developing a standard model for user interfaces which can be used across various IoT applications and devices. It will also be useful for reusing business logic on various platforms and sharing functionality between IoT devices.

3) JavaScript is open-source

Another important factor which makes JavaScript a suitable technology for the development of Internet of Things (Iot) is its open-source nature. JavaScript is free and open-source for everyone which makes possible a vast number of useful contributions to several JavaScript projects from the online community. IoT projects can greatly benefit from these various contributions which can help broaden the scope for facilitatingthe innovation of existing and invention of new IoT-enabled hardware, software and network solutions.

4) JavaScript Tools

Owing to an increased usage of JavaScript and jquery in a variety of applications and scenarios, there is a vast availability of modern development resources, such as JavaScript libraries, testing tools, prototyping tools, client-side development frameworks, server-side JavaScript APIs and more. It all makes the work of JavaScript developers easier and more effective. Moreover, JavaScript developers working on IoT projects have also got some modern frameworks at their disposal, such as CyclonJS and JerryScript.

5) Node.JS compatible Hardware Solutions

A lot of programming languages, such as GoLang, Python and others are considered to have scope in the development of IoT applications. But amongst all of these languages, Node.js is coming to the forefront. Node.js allows companies to make use of JavaScript in a variety of ways in IoT. One can develop JavaScript-compatible hardware devices with support for Node.js and IoT. Moreover, a range of hardware solutions in the world of IoT, such as Raspberry Pi, Espruinoand others offer support for Node.js. There are already thousands of npm modules developed to further extend the scope of Node.js in IoT. Besides, there are JavaScript-only microcontrollers, such as Tessel 2, which also leverage the power of Node.js technology and are extremely useful in IoT projects.

6) JavaScript is Growing

Unlike other programming languages, the scope of JavaScript has improved exponentially over the last few years. JavaScript, which was initially used as a scripting language for browsers has now grown in to a full-fledged, front-end web development technology along with HTML5 and CSS3. Moreover, JavaScript is also implemented in other areas, such as server-side development, game development, animation and of course, the Internet of Things. There is no doubt that JavaScript has become matured as a language and is continuously improving which is good for kick starting several IoT projects that are still in their infancy.

7) JavaScript Learning Resources

Another important factor which makes JavaScript a suitable technology for the Internet of Things is the vast availability of learning resources. Following the successful application of JavaScript in various web development scenarios as well as the emergence of MEAN stack and other development platforms, JavaScript has become one of the most preferred programming languages for learning. A bunch of tutorials teaching IoT programming with Node.js and HTML5 have already begun to emerge. Considering the ever-expanding world of IoT, JavaScript is suitable and capable to meet the growing demands of companies scouting for expert developers to work on IoT projects.

Conclusion:

Internet of Things is a vast field and there is still a plenty of scope for innovation. It is true that IoT projects make use of different technologies but the power of JavaScript cannot be ignored. JavaScript is relatively a lesser complicated language than others which can simplify the Internet of Things and can help several IoT projects to become commercial and popular. The scope of JavaScript will continue to rise in the field of IoT applications in the coming future.
