Challenge Description

Welcome to the coding challenge! Your task is to implement a function that reverses a given string. Consider edge cases such as empty strings or strings with special characters.

Requirements:

The function should accept one argument: a string.
It should return the reversed string.
The solution must be efficient (e.g., O(n) time complexity).

Example:


function reverseString(str) {
  // Your code here
}

// Example usage:
// reverseString("hello") should return "olleh"

Good luck! If you encounter any issues, refer to the documentation or seek hints.
