How do I reverse an array in JavaScript?

MagicBuddy

You can reverse an array in JavaScript using the reverse() method. For example, let arr = [1, 2, 3]; arr.reverse(); will change arr to [3, 2, 1].

Does it modify the original array?

Yes, the reverse() method modifies the original array in place and also returns the reversed array.

Can I reverse a string using the same method?

MagicBuddy
MagicBuddy

No, reverse() only works on arrays. To reverse a string, you can convert it to an array, reverse it, and then join it back. For example: let str = 'hello'; let reversedStr = str.split('').reverse().join('');

Are there any other ways to reverse an array?

Yes, you can also use a loop or the reduce() method to reverse an array. Would you like an example of that?
