The slice method returns a fragment of a string.

strObj.slice(start[,end])

Description:

start subscript zero-based strObj specifies the partial index. If start is negative, treat it as length+start, where length is the length of the string.

end subscript zero-based strObj specifies the partial end index. If end is negative, treat it as length+end, where length is the length of the string.

For example:

012345

var str = "ABCDEF";

str.slice(2,4);

Result: CD
