A Flow-based programming language for universal applications.
Hlang aims to make programming easier, faster and more comfortable. It avoids coding, repetition and frustration.
- 😊 Another FBP-Inspired System, totally
Reactive. - 🚀 Powerful ecosystem, abundant internal nodes.
- 👬 Just use Node-Like
Readable|Writable|TransformStream API to become a node developer. - ✊ Production-ready and Enterprise-ready, High Performance.
