Summary of Changes

Hello @xusd320, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves an issue where the generated WebAssembly (WASM) import object was malformed due to a missing comma in its string representation. The fix ensures that the WASM runtime can correctly parse and utilize the import object, which is crucial for the proper instantiation and execution of WASM modules within the application.

Highlights

• WASM Import Object Formatting: Corrected the string formatting for the WebAssembly (WASM) import object by adding a missing comma. This ensures that the generated import object adheres to valid syntax, preventing runtime errors.

Code Review

This pull request fixes a bug that caused invalid JavaScript to be generated for WASM modules with multiple imports. The change correctly adds a comma to separate properties in the generated import object. My review includes a suggestion for a more idiomatic way to construct this comma-separated string in Rust, which would improve code clarity and maintainability.

This change correctly fixes a bug where invalid JavaScript was generated for WASM modules with multiple imports. While adding a trailing comma works and is valid in modern JavaScript, a more idiomatic and robust approach in Rust is to build a list of strings and then use join(", "). This avoids manual comma management and the resulting trailing comma, leading to cleaner and more maintainable code.
