What are the JavaScript style guides, if any, which you use personally / at work?

I’ve come to know of two popular style guides:

• https://github.com/airbnb/javascript
• https://github.com/feross/standard

From what I’ve read, their eslint configs have some strange rules:

• Feross’ guide recommends no semi-colons
• Airbnb’s guide is against the recommendation of usage of loops, and prefer higher-order functions like forEach.

What do you think of these style guides.? Do you use any of these, or do you have your own custom style guide that you’ve crafted for use? Sharing your eslint config files in your answers would be super awesome! Thanks! 😃
