Babel Plugin Lite Regenerator

intro

This babel plugin is a ported version of TypeScript generator transform. It can transform async and generator function to state machine using the way of TypeScirpt.

Babel uses regenerator-transform whose helper function is about 6.6kB, but that of TypeScript just is about 1.1KB. Therefore, this plugin can decrease the bundle size if the project need to polyfill.

NOTICE

• this plugin doesn't implement the prototype of generator function.
