With a proven experience in IoT device development, Webbylab experts have researched different coding options currently trending within the industry and will remain relevant in 2024. Keep on reading to find out the best programming language for IoT that can ideally work for your project today!

#1 JavaScript

JavaScript is a universal programming language used in IoT, which can be applied for both back-end and front-end processes. Among its benefits are a low entry level and many specialized coders on the market. It works ideally for the event-driven architecture and allows the scale of the projects with the most efficient time and resource (memory, RAM, CPU) consumption. 

Webbylab has been working with JS from its birth, and not without reason. A great advantage of JavaScript for IoT projects lies in building dynamic interfaces: it enables constructing a functional layout for a certain device, covering sensors of different types (boolean, string, numeric, etc.). With JavaScript, developers can describe all the elements of the device interface on the web or mobile using JSON format, the structure of which ideally works for such kind of data. 

#2 C/C++

For most developers today, C/C++ languages are challenging to learn. Because of that, the number of candidates for hire for the role of C/C++ programming engineer on the job market is relatively low.

However, C/C++ are probably the most efficient IoT language for writing firmware for IoT devices due to their high performance, portability (for instance, the ability to execute code on different systems/microcontrollers), and a large number of ready-made libraries available. 

Harnessing the C/C++ potential, Webbylab has widely used these languages for our IoT projects. To draw an example, for some of our recent IoT devices, we’ve used the basic microcontroller ESP32, the official framework of which employs C language. Utilizing the official frameworks allows IoT developers to make the most of the embedded development and enhance the device’s productivity. That is why we had no doubts about which IoT coding language to use for these types of projects. 

#3 Go

Though Go is relatively new, it’s been widely implemented across a variety of IoT projects due to its variety of benefits. In particular, this  IoT programming language provides optimized coding, which is a must-have for small computing devices with limited power and memory resources. 

What makes Go stand out from the competition among the other programming languages for IoT devices is its concurrency – the ability to run thousands of data streams simultaneously and asynchronously. Finally, it’s extremely intuitive and user-friendly, so it doesn’t require as much effort to learn as, for example, C language. 

#4 Lua

Though it’s a pretty unusual option in the list of programming languages for IoT devices, LUA language has plenty of features that can come in handy for an IoT ecosystem. It is powerful and simple enough to ensure the efficient functioning of IoT devices. 

Unlike most of its alternatives, this language is more user-friendly and flexible, requires fewer code lines for the program execution, and features a robust framework for building IoT-specific apps with IoT-centric functionalities (portability, battery efficiency, data management, etc.).

#5 ParaSail

ParaSail is a simplified language for IoT that supports parallel programming through advanced data structures while maintaining high flexibility and efficiency. This language eliminates the need for numerous rules to improve coding simplicity and works perfectly for irregular computations.

What makes ParaSail really helpful in IoT is the automatic region-based storage management and generalized indexing, which are extremely important for efficient data structuring. 

#6 Python

The major advantages of Python language in development are its simple syntax feature and nearly seamless code readability. Therefore, it is an excellent option for object-oriented, structured, and functional programming and can be a good fit for IoT apps that require extensive data analysis.

Some other powerful benefits of Python that make it stand out from the list are high integrability with other IoT programming languages like Java and C++, comprehensive library, and support of diverse platforms covering Linux and Windows OS. 

#7 Java

This programming language for IoT has become trendy mainly because of its high portability. Because of its Write Once Run Anywhere (WORA) principle, Java developers can build the code on their computers and move it to any environment (smartphone, server, chips, etc.) using a Java Virtual Machine. 

In the IoT world, Java language is used for embedded development. It is object-oriented, features the least hardware dependency and supports a vast number of libraries, which makes it one of the best options for IoT solutions. 

#8 Rust

You won’t meet Rust very often among the must-have languages for IoT due to its smaller popularity. However, it’s an excellent language that covers all the benefits of C and C++ and is faster than these options. Some other characteristics of Rust that may come in handy for IoT are airtight documentation, resourceful error messages, and a solid compiler. 

For a starter or senior developer who values memory management and runtime capabilities, Rust can be the right alternative. 

#9 Swift

An experienced programmer will likely choose Swift for the IoT applications for iOS devices. This language is fast and secure and offers lots of programming benefits for IoT. Additionally, it has a simple syntax and is easy to code with, directly impacting the development speed and the quality of the result. 

So, if you were wondering what programming language is used for IoT project beyond the popular JS and C/C++, give it a try to Swift. 

#10 PHP

Initially designed for web app development, today PHP can be also used for the IoT as well. It features high flexibility at a lower cost, so that’s a decent language alternative for projects aimed to achieve the highest ROI performance.
