Unless I was very unlucky in my decisions about what and how to learn about vscode or my ability to learn has dropped more than 10-fold between the time I learned to modify Emacs and the time I tried to learned to modify vscode (which is unlikely but not impossible: it was an interval of 28 years) emacs is much easier to learn to modify than vscode is unless one is already a web dev.

Of course, if one does learn how to modify vscode, one has a skill (namely, web dev) in much higher demand on the labor market than knowledge of Emacs Lisp.
