ESLint Configuration Composer

Create a configuration builder that composes layered ESLint rule sets for different JavaScript environments.

Requirements

Build a system that generates ESLint configurations by composing base environment rules with optional style guide rules. Your system should support:

1. ESNext base configuration - Modern JavaScript linting rules
2. Node.js configuration - Extends ESNext with server-side rules
3. Style guide layer - Code formatting rules that layer on top of any base configuration

Each configuration should be a valid ESLint configuration object with:

• An extends array (for composition)
• A rules object (for ESLint rule definitions)
• Standard severity levels: 0 (off), 1 (warn), 2 (error)

Test Cases

• Creating an ESNext base configuration includes modern JavaScript rules like no-var and prefer-const @test
• Creating a Node.js configuration properly extends the ESNext configuration and adds Node-specific rules like no-path-concat @test
• Creating a style guide configuration includes formatting rules like quote preferences and indentation settings @test
• Composing multiple configurations in an .eslintrc file correctly merges rules from extended configs @test

/**
 * Generates an ESNext base configuration with modern JavaScript rules
 * @returns {Object} ESLint configuration object with rules for ES2015+ code
 */
function generateESNextConfig() {
  // IMPLEMENTATION HERE
}

/**
 * Generates a Node.js configuration that extends ESNext
 * @param {string} baseConfigPath - Path to the base configuration to extend
 * @returns {Object} ESLint configuration object with Node.js-specific rules
 */
function generateNodeConfig(baseConfigPath) {
  // IMPLEMENTATION HERE
}

/**
 * Generates a style guide configuration with formatting rules
 * @returns {Object} ESLint configuration object with code style rules
 */
function generateStyleGuideConfig() {
  // IMPLEMENTATION HERE
}

/**
 * Composes multiple ESLint configurations into a single .eslintrc file
 * @param {string[]} configPaths - Array of configuration paths to extend
 * @param {Object} additionalRules - Optional additional rules to override
 * @returns {Object} Combined ESLint configuration object
 */
function composeConfigs(configPaths, additionalRules = {}) {
  // IMPLEMENTATION HERE
