Linked Prototype Diagram
diagramThe dotted lines are implied relationships.
It's "nonsense" that
b1's implied .constructor is Foo().The above diagram is actually not complete. There are a lot of built-in objects and functions provided by the language. So the real relationship is much much more complex. The good news is that there's a lot of consistency:
All functions delegate up the prototype chain so they can use
diagramTo take away:.call(), .apply(), .bind() etc.:In these diagrams the functions
Foo(), Bar() are just distractions, what we care about are the Objects.
