How do I use arrow functions in array methods?

Arrow functions provide a concise syntax for writing functions in JavaScript. You can use them with array methods like map, filter, and reduce.

Can you give me an example of using arrow functions with the map method?

Sure! Here's an example: const numbers = [1, 2, 3]; const doubled = numbers.map(num => num * 2); This will return [2, 4, 6].

What about using arrow functions with the filter method?

Absolutely! For filtering, you can do something like: const numbers = [1, 2, 3, 4]; const evens = numbers.filter(num => num % 2 === 0); This will give you [2, 4].

Are there any benefits to using arrow functions over regular functions?

Yes, arrow functions have a shorter syntax and do not have their own this context, which can be beneficial in certain situations.
