JavaScript
You might not expect to see JavaScript on a list of machine learning programming languages, but the fact is that JS is increasingly being used for these purposes. One reason for this is that JavaScript is able to run directly in web browsers, which makes it easy to deploy machine learning models without any additional infrastructure. Additionally, recent advancements in hardware (such as GPUs) have made JavaScript an even more attractive option for machine learning due to its speed and efficiency.
The following are some of the most popular Javascript libraries / packages that are used for building machine learning models:

Java
Java is another versatile language that’s popular among machine learning engineers. Like Python, Java has a number of libraries and frameworks that make working with data easy. However, one advantage that Java has over Python is that it’s faster to execute. This can be important when you’re working with large datasets or training complex machine learning models.
The following are some of the most popular Java libraries / packages that are used for building machine learning models:

MATLAB
MATLAB is a commercial programming language that’s used in a variety of industries, including finance, automotive, and aerospace. MATLAB is popular among machine learning engineers because it has a number of built-in functions for working with data, matrices, and algorithms. MATLAB is also widely used in academia, so if you’re looking to pursue a career in machine learning research, MATLAB would be a good language to learn.
Octave
Octave is an open-source programming language that’s similar to MATLAB. Octave is used for numerical computation and has a syntax that’s similar to MATLAB. Octave is a good choice if you want to use a MATLAB-like language but don’t want to pay for the commercial version of MATLAB.
Scala
Scala is a relatively new language that combines features of both object-oriented and functional programming paradigms. Scala is also fully compatible with Java, which means that any Java code can be run in Scala without modification. That makes Scala a good choice for projects that need to interface with existing Java codebases. Scala is also fast and scalable, making it well-suited for big data applications like machine learning. However, Scala can be more difficult to learn than some other languages due to its complex syntax.
C++
C++ is a high-performance language that was originally designed for system programming tasks like operating system development and video game development. These days, C++ is still used for those sorts of tasks but has also found new life in applications like machine learning where speed is critical. C++ can be difficult to learn due its complex syntax and error-prone nature (e.g., memory management), but it can offer significant performance advantages over interpreted languages like Python or Java when used correctly.
Julia
Julia is a newer language that’s specifically designed for scientific computing. It combines the ease-of-use of Python with the speed of C++ to create a language that’s both powerful and easy to learn. Julia also has a number of excellent libraries for machine learning, such as Flux and Knet. However, because Julia is still relatively new, there aren’t as many resources available for those just starting out.
Conclusion
There are many different programming languages out there, but not all of them are well-suited for machine learning tasks. If you’re looking to get started in this field, your best bet is to learn one of the two most popular machine learning programming languages: Python and R. Each has its own unique advantages that make it well-suited for specific tasks related to machine learning. Whichever language you choose to learn, though, be sure to take advantage of the wealth of resources (including online courses and tutorials) that are available to help you get up to speed quickly.
