Differences to non-lively Development
Disadvantages
■ no separation between IDE and runtime environment leads to:
■ risk of damaging environment
■ debugging with developer console of browser
Advantages
■ easy inspection of objects (for exploring behaviour/state)
■ discover features by creating example objects and playing around with them
■ no context switch between IDE and runtime environment
■ no page reloads, immediate feedback■ easy reusability/sharing of parts via partsbin
