For instance:
var test
//would return t

Answer 1

var string = "test";
var result = string.charAt(0)
// returns character ar position 0 of string. 0 is 1st character.

If you don't know the position:
var string = "test";
var result = string.indexOf("t");
// returns 0, the position of the first match of t.
// returns -1 if not match is found.

Note: like arrays string start indexing at 0
var str = "test";
alert(str[0]); // alerts t
or
alert(str.charAt(0)); // alerts t

To find the certain position

"test".split("").indexOf("t");
