NI's TypeScript ESLint Shareable Config

module.exports = {
    rules: {
        /*
            The following are extension rules that replace core JavaScript rules to support
            TypeScript.
            * When upgrading, changes to these rules can be identified in the typescript-eslint
              changelog under features and breaking changes:
              https://github.com/typescript-eslint/typescript-eslint/tree/main/packages/eslint-plugin#extension-rules
            * In addition, the `npm run dev-print-typescript-props` command can be used to list
              the expected extension properties.
            * The value of the extension properties should match the value chosen by the
              JavaScript / NI configuration.
