What are some useful array methods introduced in ES6?

ES6 introduced several useful array methods like map, filter, and reduce. Would you like to know how to use them?

Yes, can you explain how the map method works?

Sure! The map method creates a new array by applying a function to each element of the original array. For example, const doubled = arr.map(x => x * 2); doubles each element.

What about the filter method?

The filter method creates a new array with all elements that pass the test implemented by the provided function. For instance, const evens = arr.filter(x => x % 2 === 0); returns all even numbers.

Can you give me an example of the reduce method?

Absolutely! The reduce method executes a reducer function on each element of the array, resulting in a single output value. For example, const sum = arr.reduce((acc, curr) => acc + curr, 0); sums all elements.
