Managing State

The core value add of tosijs is the tosi observer proxy. It wraps around vanilla javascript object, observes changes passed through it and updates bound UI elements surgically.

To see how tosi syncs state to the UI, you should also look at bind.

The goal of tosi is to make updating the user interface essentially an O(1) operation. (A key part of this is built-in support for virtual array bindings.) It also reframes keeping state in sync with the UI as a matter of wiring state from data paths to interested elements (and, where needed, observers). This is how the Mac and NeXT UIs worked, rather than the "reactive" idea of UI = f(State), which is fundamentally flawed.
