There are two ways to access an individual character in a string. The first is the charAt() method:
return 'cat'.charAt(1) // returns "a"
The other way (introduced in ECMAScript 5) is to treat the string as an array-like object, where individual characters correspond to a numerical index:
return 'cat'[1] // returns "a"
