Yes, arrow functions can be used as callbacks in JavaScript. They provide a concise syntax and maintain the lexical scope of 'this'.

Can you give me an example of an arrow function used as a callback?

MagicBuddy
MagicBuddy

Sure! Here's an example:

const numbers = [1, 2, 3];
numbers.forEach(num => console.log(num * 2));

In this case, the arrow function is used as a callback for the forEach method.

You

Are there any situations where I shouldn't use arrow functions?

MagicBuddy
MagicBuddy

Yes, avoid using arrow functions when you need a different 'this' context, such as in methods of an object or when using the function as a constructor.
