Code Playground & Code Library 
Product Introduction 
FlyEnv v4.10.6 introduces two powerful features:
- Code Playground: Execute code snippets in multiple languages instantly
- Code Library: Store and manage code snippets for future reuse
Code Playground 
Value Proposition 
Traditional workflow requires:
- Creating temporary files in IDE
- Executing commands in terminal
- Additional compilation for some languages
FlyEnv simplifies this process to one-click execution.
