charAt() function allows you to access specific characters within a string. This method can come in handy in various coding scenarios, from data validation to parsing input values.
Before we delve deeper, let's quickly see the
charAt() method in action:
In the example above, we used
charAt() to get the character at index 7 of the string
greeting, which is 'W'. Now, let's explore this method in detail.

Here's a basic syntax of the
string: This is the string from which you want to retrieve the character.
index: This is the position of the character you want to get. If this parameter is not a number, it will be converted to an integer.
Now, let's explore some practical examples where
charAt() becomes useful:
charAt() in a Loop
This loop logs each character of the word "Iteration" to the console.
If you try to access an index that doesn't exist,
charAt() will return an empty string:
