ES6+ syntax and functional programming patterns for writing clean, modern JavaScript.

• Master arrow functions, destructuring, spread operators, template literals, and enhanced object syntax for concise, readable code
• Implement async/await and Promise patterns for handling asynchronous operations, with combinators like Promise.all and Promise.race
• Apply functional programming techniques including map, filter, reduce, higher-order functions, composition, and pure functions for data transformation
• Use modern features like optional chaining, nullish coalescing, generators, iterators, and modules for robust, maintainable applications
• Optimize performance with debouncing, throttling, memoization, and lazy evaluation patterns
