*Plug for JavaScript Patterns by Stoyan Stefanov.* Chapter 3 has a great description of primitive wrapper objects vs built-in constructors (Number). Gist is that primitives such as 42 aren't objects. Objects can have methods and properties but primitives cannot. Behind the scenes when you say 42.toString() it's creating an object that has a toString method that can then be called. So when you call the constructor with new, it gives you the object as opposed to the primitive. -- To view archived discussions from the original JSMentors Mailman list: http://www.mail-archive.com/jsmentors@jsmentors.com/ To search via a non-Google archive, visit here: http://www.mail-archive.com/jsmentors@googlegroups.com/ To unsubscribe from this group, send email to jsmentors+unsubscr...@googlegroups.com
