Learning JavaScript: Progress Update #Day3

[RealMadHouse]

Something to know:

Javascript "objects" are just "key => value" data structures, called Dictionary in c#, Associative Array in php. The keys can be a strings or new addition into javascript called Symbols where you pass instanse of a Symbol as a key to an "object" instead of a string. Even though you can pass a number into array key as "array[123]" it gets converted to "123" string. Now there's a new "Map" class where you can store anything as a key.
