According to KD Nuggets, Steve Jobs, CEO of Apple, once considered Java to be a dead language, but based on its recent use in IoT development, it makes for quite a lively corpse. The versatility of Java, as well as the fact that many computer science programs tend to utilize it as their primary language, have contributed to its popularity. Java's usefulness comes from the integration of the Java Virtual Machine (JVM). An operating system running the JVM can execute any Java application without having to worry about compatibility problems. Current iterations of Java included on IoT devices run on a scaled down version called Java SE Embedded which is a close approximation to the standardized Java Standard Edition (Java SE). In Java SE Embedded, the majority of classes dealing with displays are completely removed since most IoT devices are configured to run 'headlessly' and output is done directly to the network.
Python has long been a favorite among both young and experienced coders. many programmers who are only now entering the workforce grew up on Python, using it in a variety of applications. Python is so popular that it copped ADT Mag's language of the year in 2018. While Python isn't as portable as Java, it benefits from having a wide user base that can deal with almost any sort of problem through custom scripting. Why Python tends to be such a popular language for IoT development lies with its inclusion as the language of choice for one of the most popular controllers on the market, the Raspberry Pi as well as the fact that anyone can use a Python tutorial online to learn the language. Further development of Python has led to the creation of an even smaller version of Python called MicroPython, specifically designed to run on a board that's only a few square inches in size.
While newer coders are more familiar with the children of C in C++ and C#, the original grand-daddy of database development is still alive and kicking around on IoT devices across the world. While not nearly as simple to use or easy to learn as either Java or Python, C offers a whole other level of control over the hardware. As IoT World Today notes, C's draw is its ability to access low-level hardware making it ideal for dealing with IoT devices. Additionally, C compiles and runs much faster than other high-level languages and this has been one of its benefits ever since it came on the scene in the early days of Windows programming. There is only one major drawback to using C, and that's the amount of time debugging can take. because of the large level of punctuation included in its syntax, locating an error and why it happened can be like trying to find a needle in a haystack.
Developing for the IoT
The choice of language is purely a decision that the coder should make. Which language are you most versed in? Depending on the application you're developing, it's a possibility that different characteristics of the language may be useful. Creating IoT interfaces depends on a number of different factors, but solving problems is sort of why we got into programming in the first place. In this sense, finding the right IoT language is simply another problem we have to solve most efficiently.
