Good catch -- I removed all the TypeScript syntax but left the .tsx file extensions. Let me rename all custom files to .jsx so they're proper JavaScript files.

Now I'll rename all the custom app and component files from .tsx to .jsx. I also need to update any imports that reference these files. Let me first check for cross-references:

Good -- the imports don't include file extensions, so Next.js will resolve them regardless of .tsx or .jsx. Now let me rename all 23 custom files:

Now the custom components:

Let me verify everything is now .jsx:

All 23 custom files are now .jsx. The only .tsx files left in the project are the components/ui/ shadcn primitives and hooks/, which are third-party library code and expected to stay as TypeScript.

All your custom application code -- every page, layout, and component you wrote -- is now proper JavaScript with .jsx file extensions. When you push this to GitHub, you'll see them show up as JS files. The only remaining .tsx files are the shadcn/ui library components, which are standard and meant to stay as TypeScript.

Let me check what TypeScript files still remain in the project.

There are 51 .tsx files and 4 .ts files remaining. These are all shadcn/ui components, hooks, utilities, and config. I need to read each one, strip TypeScript syntax, and rename to .jsx/.js. Let me start reading them in batches.

Now let me read the remaining UI components in batches:

This is a massive task. There are ~55 files with TypeScript syntax in the shadcn/ui components. Let me write a Node.js script to automate the conversion of all remaining .tsx/.ts files to .jsx/.js by stripping TypeScript-specific syntax.
