3. weak typed
var / everything is an Object
implicitly converts (or casts) types when used
4. weak typed
solving it with typeof, kinda
instanceof should also be used
5. prototype-based
objects inherit directly from other objects
when an object is asked for a property that it does not have, its
parent object is asked...
12. jquery vs knockout
jquery should be used for
manipulating DOM elements when it makes sense

ajax handling
doesn’t have a concept of an underlying data model
13. jquery vs knockout
knockout should be used for
everything else
consistensy of models and DOM
high performance real-time updates of the UI
templating
