Foil 41 JavaScript String Methods - I

From JavaScript Tutorial for Certificate Course UC Web applications Certificate -- Summer 97. by Geoffrey C. Fox, Tom Scavo
Examples for String Object in JavaScript for Foil 41
The String object has one property:
myString.length gives string length in characters
JavaScript has only one type of String object, whereas Java has both String (fixed) and StringBuffer (mutable) classes
Characters are indexed from the left starting at 0 and ending with myString.length - 1
newstring = myString.substring(pos1,pos2);
returns the substring in position pos1 ... pos2 - 1
Peculiarly, if pos2 < pos1, the previous statement returns the substring in position pos2 ... pos1 - 1
