Why JavaScript is the Top Programming Languages for Building IoT Applications

The Internet of Things is a made up of a lot of different components to make things work seamlessly for its users. Software, hardware, and firmware solutions are the things that are making the Internet of Things work seamlessly together.

This is a two part blog addressing web & mobile applications for IoT programming languages that are making entry into IoT easier without creating new programming languages specifically for IoT solutions.

JavaScript is the top scripting language used to create apps on both web and mobile devices for IoT applications along with other applications.

Wikipedia defines JavaScript as a high-level, dynamic, untyped, and interpreted programming language. It has been standardized in the ECMAScript language specification. Alongside HTML and CSS, JavaScript is one of the three core technologies of World Wide Web content production; the majority of websites employ it, and all modern Web browsers support it without the need for plug-ins.

Why JavaScript is the Top Programming Languages for Building IoT Applications

JavaScript has different frameworks like Angular.JS, Angular2, ReactJS and these frameworks are used in coding to create hybrid mobile apps useful for multiple OS platforms like iOS, Android, and Windows. Angular.Js is a web application framework used to create single page applications by developers. JavaScript with Apache Cordova frameworks are used in creating cross-platform mobile applications. The applications developed using JavaScript will be mostly for user interface applications which are user-friendly, and easy to access. JavaScript is also the preferred language in the development of  Web Bluetooth Apps as per W3C group standards.

Node.js is a JavaScript open source environment used in developing different server tools and applications. Node.js allows the creation of networking tools and web servers using JavaScript. Node.js applications can run on Windows, Mac OS, and Linux platforms.

JavaScript supports physical device and the IoT  platforms and is becoming the language of choice, because of its ability to support an inter-operable platform for many different applications.

How Web Bluetooth Works to Access IoT Devices

Web Bluetooth for IoT

Bluetooth technology is making very excited, almost everyone, like tech users, developers and manufacturers, it is bringing lots of innovations by transforming day-to-day objects into IoT devices for better life.

Until now, we have had the ability to interact Bluetooth devices using only native apps. Google Chrome’s web development team regularly implement new APIs to extend new possibilities for web apps to behave an equivalent to that of native apps. Web Bluetooth API is targeted to change native app scenarios and brings Bluetooth device interaction into web browsers.

Web Bluetooth allows web developers to use Bluetooth to communicate with smart Bluetooth Low Energy devices. Similar to the Physical Web, users can interact with IoT devices when they are in range of the device. Web Bluetooth is a draft API, that allows a user to scan and select any local IoT device within range from a web page. Once the user selects a device from multiple IoT devices, a web page can directly control a device via Bluetooth Low Energy. The latest Google Chrome update has an Android enabled web Bluetooth to control IoT devices. To learn more, take a look at our previous blog post “How Bluetooth Low Energy (BLE) supports Chrome to communicate with devices over IP”.

Communicating with Bluetooth devices through a web browser provides a great opportunity for companies to launch new IoT devices. They can spend more time and money on new product development instead of a native app for different platforms.

More sensitive web APIs are switching over only to the HTTPS mode. The Web Bluetooth API is no exception, it works only on HTTPS pages. The API will not work in the background without a user approve. The user can choose a Bluetooth Low Energy device to pair with it. Once the user is connected to a BLE device, it should gather data and connect to the BLE devices. BLE provides most of its functionality through key pairs provided by the Generic Attribute Profile (GATT).

Web Bluetooth provides endless opportunities for IoT device manufacturers. We at BlueApp.io support Web Bluetooth to access IoT devices without downloading any specific native app for IoT device.
