10 Best Julia Courses for Developers
The Best Julia online courses to use Julia in data science, machine learning, and parallel computing at both beginner and advanced levels.

The Best Julia online courses to learn Julia for data science, machine learning, and parallel computing for beginners
Why learn Julia?
Julia is most recommended for use in data science, machine learning, parallel computing, data visualization due to its high performance. Julia uses LLVM - a target-independent optimizer and code generator, to compile the code and run it on different OS and architectures.
Julia is open source and has a very good developer ecosystem around it. Julia provides built-in libraries and packages that make it faster to work with scientific computing and numerical computing.
Julia is easy to use with various IDEs using built-in packages and plugins:
- Julia vscode plugin - for the VSCode
- Julia package - to run in the Jupyter notebook
- Pluto. ji package - to run in Pluti notebooks
It also solves the two-language problem, i.e, you need not design the prototype of the system first in a static language and then implement it in a dynamic language. You can directly build the system using the dynamic functionalities Julia caters us, including logging, profiling, debugging, asynchronous I/O and a package manager.
