What are some advanced uses of arrow functions in JavaScript?

Arrow functions in JavaScript can simplify your code, especially with callbacks and higher-order functions. They also lexically bind the this value, which can be very useful in certain contexts.

Can you give me an example of using arrow functions with array methods?

Sure! For instance, you can use arrow functions with the map method to transform an array. Here's an example: const doubled = numbers.map(num => num * 2);.

What about using arrow functions in event handlers?

Absolutely! Arrow functions are great for event handlers because they maintain the context of this. For example: button.addEventListener('click', () => { console.log(this); });.

Are there any downsides to using arrow functions?

Yes, one downside is that arrow functions cannot be used as constructors, and they don't have their own this, arguments, or super.
