If the string contains multiple occurrences of the character passed as a parameter, the
charAt method will return only the position of the first occurrence. If the character is not present in the string, the
charAt method shall return an empty string.
charAt method can be used with String objects, although it will also work with standard strings defined with single or double quotes, as well as with literal templates.
In this example we use the
charAt method on a standard string, getting first the character at position 0, then the character at position 2 and finally the character at position 20, which is an index that does not exist in the string:
charAt(20) // ""
charAt method works in the same way with
String objects, as we see in the following example
charAt(0); // 'J'
charAt method is case sensitive, so the J character is not the same as the j character.
