What is Juno?
Juno is a free, integrated development environment (IDE) specifically designed for the Julia programming language. It aims to combine the ease-of-use of a notebook-style environment with the productivity of a full-fledged IDE, offering real-time feedback during development. This makes it suitable for both beginners exploring Julia and experienced developers building complex software. Built on the Atom editor, Juno provides a highly customizable platform with advanced editing features. It emphasizes a "canvas programming" style for exploratory work while maintaining the robust capabilities expected from an IDE, such as profiling, debugging, and terminal access. However, it's important to note that Juno is no longer receiving feature updates, with development focus having shifted to the Julia extension for VSCode.
