IDEs in general tend to be resource intensive. Not necessarily because they need all those resources, but that cost of tech bloat was probably necessarily in order to let them ship to begin with. It's why back many programmers kept a text editor for smaller scripting or quick editing and only whipped up Eclipse/VS/IntelliJ when absolutely needed (ignoring the vim/emacs wizards who have dozens of plugins and get the best o both worlds).

VS Code is nice in that it strikes a good balance between a Text Editor and full blown IDE. Far from replacing the latter, but I can and have worked on medium sized projects exclusively in VS Code.
