fast-async

A Babel plugin that transforms ES7 async/await to Promise-based code without generators, offering 3-4x performance improvement in browsers vs Babel's default regenerator approach. Current stable version is 6.3.8 (for Babel 6) and version 7 for Babel 7 (beta). Uses the nodent library under the hood. Key differentiators: avoids generators and regenerator, supports 'spec' mode for spec-compliance, and allows runtime pattern customization. Has undergone several fixes for edge cases like destructuring and export hoisting.
