Extracting the Remainder of a String

The substring() method accepts two parameters, start and end, and extracts the substring beginning at position start up to and not including the character at position end. The first character of a string is at position 0. Here is the syntax: 
stringVar.substring(start, end)
For example, the following code should return "Doc JavaScript": 
var s = "Be sure to read Doc JavaScript biweekly columns and daily tips";
var ss = s.substring(16, 30);
The parameters start and end can be switched, as JavaScript takes the smaller value to begin the substring and the higher one to end it. Also, the second parameter may be omitted. In this case, the substring will end when the string itself is exhausted. For example, the following code should return "biweekly columns and daily tips":

var s = "Be sure to read Doc JavaScript biweekly columns and daily tips";
var ss = s.substring(31);
