Why Choose Javascript for your next IoT Project


Internet of Things has become one of the most popular technologies in the world. Various companies around the world have started utilizing the features of the Internet of Things to provide better services to their customers.

Moreover as per the latest research report of Microsoft, which is based on the IoT and made to offer the global overview regarding IoT, stated that over 85% of respondents will soon adopt IoT, and around three-fourths have also kept their projects under planning. Apart from this, 88% of respondents also consider IoT as the most essential factor behind the success of their business.

There are a wide number of programming languages available in the market which can be used for IoT development. The selection of a language will have a lot of impact on your IoT project as you have to deal with a lot of sensors and other hardware devices.

IoT lifecycle consists of a collection and management of data from a big network of sensors as well as devices. Also, this data is analyzed as well as processed in real-time. In short, to operate an IoT lifecycle with ease you have to look for a programming language that enables you to build communication between various devices and doesn’t break any connectivity in the entire structure.

Here, we recommend you consider JavaScript Development. Why? There are some strong reasons to choose JavaScript for IoT development. Primarily, one common reason to choose JavaScript for IoT application is that it is open a wide number of opportunities for JavaScript Developers.

Now, we will provide some essential benefits of using JavaScript for developing IoT solutions.

Reasons to Consider JavaScript for IoT project


Node.js is an open-source, cross-platform, JavaScript runtime environment which is beneficial to create data-focused and real-time web and mobile apps.

The Server-side implementation is possible with Node.js. Also, its Event-Driven, Non-blocking I/O Model is best for building and handling web applications that communicate in real-time.

Node.js is capable of handling a bunch of requests that are generated from different devices such as sensors, beacons, transmitters, and lastly motors.

Node.js also consists of NPM (Node Package Manager) which holds the collection of biggest repositories in the world such as Arduino Controller, Raspberry Pi, and much more.

Various startups, as well as tech giants, are harnessing the power of Node.js to develop a network of different devices, sensors, and smartphones that can be handled as well as updated remotely.

Several leading companies around the world that use node.js for developing IoT projects include Microsoft, Netflix, Samsung and much more. In short, you can increase the speed of your IoT project by considering JavaScript Development services.

Memory Management

In programming languages like C, developers have to allocate & deallocate methods with the help of methods such as malloc(), calloc(), realloc(), and free(). But in the case of JavaScript, you don’t have to explicitly allocate or release memory.

JavaScript consists of automatic memory management known as garbage collection. Here the things are formed and then freed instantly when not needed.

The garbage collector feature enables developers to work undividedly on the development part instead of wasting their time in memory management. Somehow, automatic freeing of memory helps to develop a secure IoT application.

Event-Driven Applications

JavaScript works well with event-driven applications. There are certain kinds of applications where devices listen to different events and respond to a particular event.

A node consists of an “event loop” which enables you to operate a wide number of tasks without looking to wait for every task to get over. You can receive and reply to events, then wait for a certain time to get a callback for a specific event that alerts you as soon as it gets completed. This makes it suitable for you to respond to events on-the-go, controlling a wide number of tasks parallelly and also enable different devices to respond as they happen.

The event-driven programming feature of JavaScript also helps to save battery power.

Libraries, Plugins, and APIs

JavaScript possesses a wide number of libraries, plugins, and APIs which can be thoroughly used for IoT solutions. Moreover, a wide range of npm modules available in JavaScript can be used in client and server-side programming.

JavaScript utility libraries such as Underscore.js, traverse, lodash, and Async can be utilized to resolve some standard issues in multiple devices. Several robust functions are present in the above modules which can be helpful for you for building IoT applications using JavaScript Development.

One of the most popular JavaScript modules that is essential in IoT is This module is used to get real-time event-based communication in different devices.


One of the most essential reasons you should consider JavaScript for your IoT project is because of its free and open-source nature. Due to this, there are numerous contributions to different projects from its huge community of developers across the globe.

Any JavaScript Development Company or a JavaScript Developer can take advantage of these contributions to upgrade their current IoT application or for creating a new IoT software, hardware or a network solution.

Ease to Learn & Implement

JavaScript is quick to learn as well as implement programming language if you compare it with popular languages like C++, Ruby, and Python. JavaScript is a leading programming language that simplifies a lot of tasks while developing an IoT application. JavaScript operates easily in a wide number of environments, therefore it is best in case of gateways and cloud.


The Internet of things is a very massic industry and there is a lot of room for innovation. It is absolutely correct that various programming languages can be utilized for developing different IoT projects. However, JavaScript is one of the leading languages used by developers across the globe for Front-end and Back-end development.

Hence, this makes perfect sense to utilize JavaScript in devices that are already ruling the internet world. Apart from this, reasons such as memory management, open-source nature, huge libraries, node.js, and much more indicate that JavaScript is best suited for IoT projects.

If you are not familiar with JavaScript, then you can reach out to a professional JavaScript Development Company. They will provide you the best IoT solution as per your business needs and goals.
