These are my day-to-day VSCode plugins:
Sublime Text Keymap and Settings Importer.
This extension is a must have if you come from Sublime Text.
Prettier - Code formatter.
This is the extension I can't live without. Automatically formatting your code upon save. It saves so much time!
NightSwitch-Lite.
Automatically change the theme based on the time of the day, so your eyes can rest in the evening.
Auto Rename Tag.
Automatically update the closing tags in HTML/ JSX/ XML/ whatever, just like Chrome DevTools does.
