from instability and inefficient data retrieval as a result of using
HTML5. Facebook would soon provide a better mobile
experience, he promised.
Jordan Walke discovered a method at Facebook for creating
iOS UI components from a background JavaScript thread,
which served as the inspiration for the React web framework. In

native apps using this technology, they made the decision to
host an internal hackathon.
