eslint/Environment setup Video?

I'm on the Full Stack JS Developer course and in the last few videos the linting tool, eslint, has been put into the files and not mentioned whereas earlier videos in the course didn't use any code-formatters.

I have a rough idea of how they work from other tutorial videos but wondered if you might create a short video set on them? (unless you already have)

I appreciate you can always look up the docs but I still wonder for example, why you chose the configuration that you did? and why you're only including them now? Does eslint get used in the standard boilerplate when setting up these examples by default?

I also used to have this installed globally before removing it. How do people work with this in teams and real-life considerations like this? For example, my first Treehouse project received some feedback about leaving the last comma in object literals, where in fact this eslint Airbnb style put one on the end of the last key-value pair automatically.

Not so much a question as a series of thoughts.
