1. Destructuring Magic: Unpack arrays and objects with ease:

const [name, age] = ['Alice', 30] // name = "Alice", age = 30
const { title, author } = book // title = book.title, author = book.author

2. Optional Chaining Rescue: Avoid pesky undefined errors:

const user = { name: 'Bob', address: { city: 'New York' } }
const city = user?.address?.city // city = "New York" (if address exists)

3. Template Literals: Build dynamic strings smoothly:

const name = "Alice";
const message = `Hello, ${name}!`; // message = "Hello, Alice!"

4. Arrow Functions: Keep things concise:

const numbers = [1, 2, 3];
const doubled = numbers.map(number => number * 2); // doubled = [2, 4, 6]

5. Spread Operator: Merge arrays and objects effortlessly:

const colors1 = ["red", "green"];
const colors2 = ["blue", "yellow"];
const allColors = [...colors1, ...colors2]; // allColors = ["red", "green", "blue", "yellow"]

6. Short-Circuit Evaluation: Simplify conditional statements:

const isLoggedIn = true;
const content = isLoggedIn && <div>Welcome!</div>; // content displays Welcome! if isLoggedIn

7. Ternary Operator: Condense expressions:

const age = 18;
const message = age >= 18 ? "You can vote!" : "Not yet eligible"; // message depends on age

8. Rest Parameters: Collect remaining arguments:

const age = 18;
const message = age >= 18 ? "You can vote!" : "Not yet eligible"; // message depends on age
