• let & const: block scope, non-reassignable variables
• Arrow Functions: shorter syntax, this binding behavior
• Template Literals: backticks syntax, string interpolation, multiline support
• Destructuring: object destructuring, array destructuring, function parameter destructuring
• Spread & Rest Operators: ... for arrays and objects
• Default Parameters
• Enhanced Object Literals
• Symbols: unique identifiers

Template Literals

Multi-line strings and variable interpolation using backticks

const name = 'Alice';
const greeting = `Hello, ${name}!`;

Default Parameters

Assign default values to function parameters

const greet = (name = 'Guest') => `Hello, ${name}`;

Destructuring

Extract values from objects/arrays

const person = { name: 'John', age: 30 };
const { name, age } = person;

const nums = [1, 2, 3];
const [first, second] = nums;

Spread and Rest Operators

• Spread (...): Expands arrays/objects
• Rest (...): Collects remaining elements
