Ivy is a complete rewrite of the compiler (and runtime) in order to:

• 🚀reach better build times (with a more incremental compilation)
• 🔥reach better build sizes (with a generated code more compatible with tree-shaking)
• 🔓unlock new potential features (metaprogramming or higher order components, lazy loading of component instead of modules, a new change detection system not based on zone.js…)
