Works great, but.. 
In case of exception it’s hard to figure 
out what happened 
Many inputs, many code paths
The synchronous design 
Rendering 
Global State 
{:foo 
“bar” 
:bla 
“bla” 
…} 
View 
Mutators 
Events 
Change data
Works great, and.. 
We have only one global code path 
We have a full state of the app, 
when bad things happen
