Hey everyone! I'm trying to figure out how to reverse a string in JavaScript, but I'm hitting a snag with my code. Here's what I've written:
```javascript
const str = "hello";
const reversed = str.reverse();
console.log(reversed);
```
I was expecting to get "olleh" as the output, but instead, I'm facing an error. If anyone has any tips or solutions, I would really appreciate it!

You might want to consider using TypeScript for this. It can help catch errors like this one by informing you that `reverse` isn’t a function that exists on strings. But if you're using plain JavaScript, the error message you get "Uncaught TypeError: str.reverse is not a function" does suggest that something's off with your approach.
The issue is that there’s no `reverse()` method for strings in JavaScript. Instead, you can convert the string into an array, reverse that array, and then join it back into a string. Here's how you can do it:
```javascript
const str = "hello";
const reversed = str.split('').reverse().join('');
console.log(reversed);
```
This should give you the expected output of "olleh"!
