What are some advanced techniques for manipulating arrays in JavaScript?

There are several advanced techniques, such as using the map, filter, and reduce methods. Would you like examples of each?

Yes, please provide examples for map and reduce.

Sure! The map method creates a new array by applying a function to each element. For example: const doubled = arr.map(x => x * 2);. The reduce method accumulates a value by executing a reducer function on each element. For example: const sum = arr.reduce((acc, curr) => acc + curr, 0);.

What about using filter? Can you show me an example?

Absolutely! The filter method creates a new array with all elements that pass the test implemented by the provided function. For example: const evens = arr.filter(x => x % 2 === 0);.
