VSCode was late to the party. Atom and Notepad++ were before them. Don't forget eMacs or VI that were first in the text IDE modes for multiple languages.

20 years ago we didn't have Youtube or online courses to learn. Just websites and forums and Yahoo Clubs/Groups. As soon as Visual BASIC got a service pack the old books were obsolete and you had to read on MSDN or the forums or the Yahoo Clubs how to deal with the API changes and language changes. Which management never understood and confused MSDN with MSN.
