Problem Statement:

Write a JavaScript function to reverse a given string.

Solution:

We take an input string and split it into an array of characters using split(“”).
We reverse the array using reverse().
Finally, we join the reversed array back into a string using join(“”).

Solution Explanation:

1. The split("") method converts the string into an array of characters.
2. The reverse() method reverses the array.
3. The join("") method converts the array back into a string.

Solution:

      function reverseString(str) {
            return str.split(“”).reverse().join(“”);
     }
    console.log(reverseString(“hello”)); // Output: “olleh”

Example Output:
Input: “hello”
Output: “olleh”
