FastDom
Eliminates layout thrashing by batching DOM measurement
...When any module requires 'fastdom' they get the same instance back, meaning FastDom can harmonize DOM access app-wide. Potentially a third-party library could depend on FastDom, and better integrate within an app that itself uses it. It's very important that all DOM mutations or measurements go through fastdom to ensure good performance; to help you with this we wrote fastdom-strict.
