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.
