Learn how the JavaScript charAt() method returns the character at a given index in a string, and why an out-of-range index gives you an empty string back.

Return the character at the index i
Examples:
'Flavio'.charAt(0) //'F'
'Flavio'.charAt(1) //'l'
'Flavio'.charAt(2) //'a'If you give an index that does not match the string, you get an empty string.
JavaScript does not have a “char” type, so a char is a string of length 1.
