In the case of .js files I would recommend using both Eslint and Prettier.

You can set up Prettier as an Eslint rule using the following plugin:

https://github.com/prettier/eslint-plugin-prettier

And in order to avoid conflicts between Prettier and Eslint, you can use this config:

https://github.com/prettier/eslint-config-prettier

Which turns off all Eslint rules that are unnecessary or might conflict with Prettier.
