VSCode has a system for different extensions to report problems. The editor
will visually flag those problems in the editor with a red squiggly underline.
It will also list them in the Problems tab of the bottom tray (hit Cmd+j to
pop that tray open).
If there are some active problems in your current file, you can jump right to them.
Hit F8 and you'll jump to the next problem after wherever the cursor is. Hit
F8 again and it will go to the next one.
Want to track back through the file? Hit Shift+F8 and you'll jump to the
closest problem behind the current cursor position.
Using these two, you can quickly survey the current problems in your file before deciding how to proceed.
