Hi @rrit - thanks for the PRs. The first one sounds like a good improvement. Were you able to measure the performance impact? How much time does it save?

As @sam said, the maintainability of the second one is a little concerning. It looks like it’s a copy/paste from the Ember source code? Did you change something in order to improve performance?
