Prettier is the best thing I ever used in my development workflow!

Pros:

• Format codes in JavaScript, JSON, and TypeScript also！
• Used plugins in Sublime and VSCode with edit on save, to format the codes for you.
• can customize on your preferred setting (tabs/space, semicolon or not)
• save tonnes of time on formatting, following standards given

Cons:

• It does not being support in VIM mode, but there is CLI tools to format it.
• When you don't want to format a certain line, it doesnt work like that.
