Modern JavaScript includes powerful syntax improvements that make code more readable and expressive.

• Arrow functions: const add = (a, b) => a + b
• Destructuring: const { name, age } = person
• Template literals: \Hello, ${name}!\``
• Spread operator: [...array1, ...array2]
• Default parameters: function greet(name = 'Guest') {}
• Classes: class User { constructor() {} }

Refactor old-style JavaScript to use ES6+ syntax. Use arrow functions, destructuring, and template literals.
