• Everything in JavaScript is an Object. Even functions
• Every object is always mutable
• The dot operator is equivalent to de-referencing by hash (e.g., foo.bar === foo["bar"])
• The new keyword creates an object that class constructors run inside of, thereby imprinting them
• Functions are always closures (combine w/ previous rule to create OOP)
• The this keyword is relative to the execution context, not the declaration context
• The prototype property is mutable
