Configuring and Running ESLint.md

You've probably at least heard of ESLint before, but just in case you haven't. ESLint is tool for performing static analysis on your code and finding places where you're code might have some unexpected edge-cases. On it's best days, it can be a powerful tool to help you enforce best practices in your codebase. On it's worst days, it can annoy your co-workers with pendantic formatting issues and other stylistic nitpicks.

To install eslint:

npm install -D eslint

Next, you'll need to initialize a configuration file.

npm init @eslint/config
