Object references considered helpful

Episode 70 // The EmberMap Podcast

Sam and Ryan talk about a stale state bug in a React app, and how Ember's decision to use object references helps developers avoid these sorts of bugs. They also talk about how Ember's framework magic can sometimes make folks feel ill-equipped to work in the larger JavaScript ecosystem, despite being extremely pleasant. Then they answer some listener questions.
