|6.1.1.The String Type|
The String type is the only primitive type that doesn't have a definite size.
A string can be used to store zero or more Unicode characters.
Each character in a string is given a position.
The position starts with the first character in position 0, the second character in position 1.
The position of the final character in a string is always the length of the string minus 1.
String literals are specified by using either double quotes (") or single quotes (').
var sColor1 = "blue";
var sColor2 = 'blue';

|\unnnn||A Unicode character represented by hexadecimal code nnnn (where n is a hexadecimal digit 0-F)|
