There have always been other solutions though. Someone here mentioned eclipse as a FOSS solution, but there are others. Even vim and kate have pretty good language comprehension thanks to working with language servers. Likewise products like JetBrains while they can be expensive are very good pieces of software. I actually don't even use VSCode that often anymore thanks to Kate and the JetBrains suite. VSCode itself is open source and you can use one of the pure open source builds, or any of the other programmers text editors that exist.
