• Refactor code to comply with eslint 9.x
• Remove unnecessary any
• Replace any with `unknown when possible

Summary of using any or unknown

• Use unknown for better type safety and explicit checks
• Only use any if you truly need unchecked, flexible behavior

Summary of linting configuration

ESLint packages used:

• eslint –> The core ESLint package. It is the base linter.
  NOTE: Styles have moved from eslint -> @stylistic/eslint-plugin (js and ts)
  Built-in stylistic rules for JavaScript and Typescript
  We are still using legacy config, so we need to install v3.x with
  npm i -D @stylistic/eslint-plugin@3

• @stylistic/eslint-plugin -> Used for general stylistic rules, which can be
  applied to both JavaScript and TypeScript.
  See here for additional information on ESLint Stylistic Stylistic Formatting
  for ESLint https://eslint.style/

• eslint-plugin-n -> This package provides additional ESLint rules for Node.js
  Originally the these were provided by the eslint-plugin-node that it is
  no longer maintained

• @eslint/js –> This package provides core ESLint rules for JavaScript. It’s
  necessary to allow ESLint to enforce JavaScript best practices.

• typescript-eslint –> Tooling which enables the use of TypeScript with ESLint.
  This package is the entrypoint to consume additional tooling with ESLint.
  The package exports the following:
  config -> A utility function for creating type-safe flat configs
  configs -> Shared ESLint (flat) configs
  parser -> A re-export of @typescript-eslint/parser
  plugin -> A re-export of @typescript-eslint/eslint-plugin
  Notes: We still need to install the parser and plugin separately

  • @typescript-eslint/parser –> This parser allows ESLint to understand TypeScript
    syntax. Without it, ESLint won’t be able to process TypeScript files correctly.
  • @typescript-eslint/eslint-plugin –> This ESLint plugin provides additional
    TypeScript-specific rules.

Optional package used that are very useful for best practice:

• eslint-plugin-unicorn –> A plugin that provides a collection of additional
  rules that enforce best practices and modern JavaScript standards. It’s
  optional but useful for enforcing stricter code quality.

• eslint-formatter-stylish –> A package that provides a stylish formatter for
  ESLint. It’s optional but useful for a more readable output.

May need to use the chai plugin in the future
npm install --save-dev eslint-plugin-chai-friendly
And configure it into plugins: { "chai-friendly": chaiPLugin }
