/**
 * @file eslint.config.mjs
 * @description ESLint configuration file that sets up linting rules and environments for JavaScript and Jest.
 * 
 * This configuration extends the recommended ESLint rules for JavaScript, includes Jest-specific linting rules,
 * and integrates environment globals for Node.js and Jest.
 * 
 * Key features:
 * 
 * - **Globals**: Sets global variables for Node.js and Jest environments.
 * - **Plugins**: Includes the `eslint-plugin-jest` plugin for Jest-specific linting rules.
 * - **Recommended Rules**: Applies the recommended configuration from the ESLint `@eslint/js` package.
