This is either false, or you didn’t understand the environment you were working in.
You have to explicitly turn on the setting to have VSCode reformat on save, it’s not on by default, and when it is on, it’s there for a reason, because having software developers that do not all follow the same standard for code formatting creates unpredictable needless chaos on git merge. This is literally ‘working as a software developer on a team 101’.
Congrats, if you’re trying to write software from your phone you should be fired as a software engineer.
Again, it is stupid as fuck for any software developer to use VIM. If you have to telnet into some random bullshit server for whatever reason you’re obviously in a different position. But real, good, maintainable software is not written and built by teams insisting on creating learning curves for no reason.
