Node.js Azure Function programming model V4 Preview

Microsoft has announced the preview of Azure Functions version 4 for the Node.js programming model. This update brings several enhancements and new features to the platform, including:

1. Flexible folder structure: The V4 model removes the strict directory structure and gives users the flexibility to organize triggers
2. Define function in code: The V4 model uses an app object as the entry point for registering functions instead of function.json files.
3. New HTTP Types: In the V4 model, we’ve adjusted the HTTP request and response types to be a subset of the fetch standard instead of types unique to Azure Functions

This preview release aims to gather user feedback to refine and enhance the platform before the official release. Users are encouraged to provide their input and report any issues they encounter.

Now V4 Programming model landed in the VS Code.
