How can I use advanced array iteration methods in JavaScript?

You can use methods like map(), filter(), and reduce() for advanced array iteration. Would you like examples?

Yes, please provide examples for each method.

Sure! For map(), you can transform an array: const doubled = arr.map(num => num * 2);. For filter(), you can select elements: const evens = arr.filter(num => num % 2 === 0);. And for reduce(), you can accumulate values: const sum = arr.reduce((acc, num) => acc + num, 0);.

What are the differences between these methods?

map() creates a new array with transformed elements, filter() creates a new array with selected elements, and reduce() returns a single value by accumulating results.
