Here’s how to use these methods to reverse a string:
In this example, the `split(”)` function is used to separate the string into an array of characters. The `reverse()` function is then used to reverse the order of the characters, and the `join(”)` function is used to join the reversed characters back together into a single string.
Using a For Loop
In this example, the loop starts at the end of the string (at str.length – 1) and works its way to the beginning (when i is greater than or equal to 0). It appends each character it encounters to the reversed string, effectively reversing the order of the characters.
Here’s how you can use recursion to reverse a string:
In this example, the recursive function `reverseString` continues to call itself with a progressively smaller substring of the original string (`str.substr(1)`) until the substring is empty (`str === ”`). At each recursive call, it adds the first character of the current substring (`str.charAt(0)`) to the end of the new string, effectively reversing the order of the characters.
