Reverse a String

Reverse a String

To reverse a string, you can split the string into an array of characters, reverse the array, and then join the characters back into a string.

Algorithm:

1. Convert the string into an array of characters.
2. Use the reverse() method to reverse the array.
3. Join the array back into a string using the join() method.
4. Return the reversed string.

Example:

function reverseString(str) {
    return str.split('').reverse().join('');
}

// Example usage
console.log(reverseString("hello")); // Output: "olleh"
console.log(reverseString("JavaScript")); // Output: "tpircSavaJ"

This method has a time complexity of O(n), where n is the length of the string.
