It is estimated that by 2020, more than twenty four-billion devices would have been connected to the internet that is four devices for every human on earth. These smart devices altogether make up the Internet of Things (IoT).

The internet of things otherwise known as IoT are smart devices or appliances that communicate with each other over a network. It is basically smart devices sharing data over a network. These smart devices include smartwatches, smart TVs, cars, thermostats, and so on.

The IoT offers us the means to collect, measure, and analyze data to create solutions.

IoT is increasingly becoming a part of the work and home environment. Businesses are using it to improve their overall efficiency, such as decision making, customer support, and so on.

The majority of these smart devices, “smart things” use the same programming language that mobile devices and PCs use; however, there are some significant differences. Knowing the most suitable programming language for IoT is, therefore, essential.

This is an ideal software because its code can be produced and debugged on your desktop before it is moved to a chip with the help of the Java Virtual Machine. It can also run on tiny machines and not just in places where JVM’s are common; it is also very portable.

Java’s language was borrowed from Eiffel, Mesa, C, and C++; therefore, if you are familiar with any of these other languages, you can quickly learn to program with JAVA. It is also one of the most common languages for coding because it is object-oriented with built-in capabilities that are very useful for IoT apps.

Since the year 2000, it had been available on embedded devices and other handsets in JAVA ME or micro edition version. The latest features of JAVA are on the JAVA 8 platform.

2. C++

If you can program with this language, you can program with languages like C#, D, Python, Java, and other languages. C++ is an object-oriented preprocessor which allows it to run high-level languages. A lot of developers love this language even though mistakes can be made easily using it.

This language is one of the best for developers who are trying to extend their programming code for embedded code and IoT because it allows for different layers of objects, layers, and abstractions in standard embedded programming and Linux languages.

3. Python

This is one of the most accessible programs for people that want to use and understand IoT projects. Previously this language was used mainly for web applications. This high-level scripting language has a vast number of handy libraries allowing work to be completed with few numbers of codes.

This language is terrific for data analysis, which is an integral part of IoT systems because it allows for readability with syntax while keeping size intact. Of recent, most of the popular microcontrollers make use of this language. Another advantage of this program is that it allows applications to collect and manage complex data conveniently. 

There are also smaller versions of this language, like the MicroPython board and software package. It is the ideal language for people who want to develop anything for Amazon’s Alexa.

4. JavaScript

This is the fourth favorite for developers, as stated in the 2018 survey by IoT developers. Although it was initially used as the primary programming language for HTML and web browsers, it is now one of the best languages for IoT. 

This scriptwriting language shares language libraries with Java, although it took a few parts from other languages like C and Python. This language helps to make devices interoperable, which is very important in IoT.

Tessel and Espruino are microcontrollers that run this language from the beginning.

5. C

This is a common and vital language among IoT developers. It works well with every single detail of the program giving you the ability to make changes to necessary coding. This is the ideal language for large devices which have operating systems.

This programming language has been the foundation for other languages; therefore, it is only ideal that it is a popular one among developers that undertake IoT projects.

6. Swift

This programming language is known for its wide use in creating apps for Apple’s iOS and macOS devices. If you, therefore, want to work with these devices, you have to learn this language.

Apple is trying to become prominent in the IoT at home network. It is common knowledge that Apple is building libraries and infrastructure that will handle the majority of the work so that developers will be able to pay more attention to the task while the HomeKit platform handles the integration.

7. Go

This embedded language that was developed by Google shares a lot of similarities with C. This language facilitates the ability for devices to work together, allowing data to be sent and received in many channels simultaneously.

There is, however, the possibility of data loss if it is not managed correctly in the phase of coding. The language, however, continues to evolve; therefore, a change might occur in the future.

Benefits of IoT

Internet of things presently offers a lot of benefits to both individuals and organizations; some of the benefits are:

  • Improve overall productivity
  • Saves energy and resources
  • Saves time and money
  • It improves the wellness of individuals
  • Provides high-quality data
  • Allows for making the best decisions


Smart devices play very significant roles in our everyday life and cannot be taken for granted. From using it to access translation services like The Word Point to help us not get lost when using Google maps. IoT makes sure we continue to benefit significantly from these devices. The above-compiled list represents the top programming languages developers love using.
