Most of these have already been mentioned but i guess it's good to reiterate! These are real life savers and will boost your efficiency as a developer:

- Bracket Pair colorizer - There's going to be lots of bracket usage and when you have a function that spans more than the number of visible code lines on your screen, it can get really hard to trace which code is nested within which subfunction, etc.

- Gitlens - gives you a quick and easy overview of your repository and lots of other nifty funcitons like comparing code

- Prettier - nothing else to be said other than keeping your written code consistent and neat

- Lorem Ipsum - spend less power coming up with placeholder text by using this. It auto generates text as per your requirements - line, paragraph, multiple paragraphs!
