eslint-plugin-unicorn VS eslint-config-xo

I recently scanned out codebase with https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/prefer-set-has.md and found many instances of potential "accidentally quadratic" uses of array.includes instead. gas a nice autofix to convert to set. there are some fun and sometimes useful lint rules out there...

There’s an ESLint rule for that (albeit in a plugin)

Many popular eslint configs have even introduce rules to warn on its usage for these very reasons.

eslint-plugin-unicorn

I find eslint-plugin-unicorn package pretty useful for updating old code. With IE11 dead and NodeJS v12 LTS sunsetting soon, it's a brave new world.

Default parameters should not be passed to a function through an object literal. The foo = {a: false} parameter works fine if only used with one option. As soon as additional options are added, you risk replacing the whole foo = {a: false, b: true} object when passing only one option: {a: true}. For this reason, object destructuring should be used instead. Linter rule

Based on your requirements and environment, answer the questions accordingly. At least with eslint version 8.0.1, you are only presented with 2 style guides: standard and XO. Personally, I prefer the standard styling guide but at any give time, it is a personal choice and as such feel free to choose any from a bunch of available options. Once all dependencies are installed, ensure that you have the following packages added as devDependencies to your project:
