How does this actually work? First of all, Xojo is a programming language (you can download and review its documentation here). However, all the functions offered by Xojo seem to be a bit too good to be true.
Xojo is suitable for creating apps that run on Windows, macOS, Linux, iOS, and Raspberry Pi. The documentation presents this lightweight programming language as a suite of utilities meant to be built on top of Visual Basic (a programming language under Microsoft's proprietary right) and Java.
It is an integrated development tool and a programing language in itself. We could start by saying a few things about Xojo. An unconventional approach that is suitable for those who need to develop multi-platform apps Xojo enables access to an entire suite of tools for creating, running, debugging, and building applications from within the same development environment.
