[microsoft/vscode] "Ran Playwright code" Input code is syntax highlighted as if it were JSON, but it's JavaScript

### ROOT CAUSE The Playwright code is being incorrectly interpreted as JSON due to the file's extension or VS Code's language settings. The file likely has a `.json` extension or VS Code is set to treat it as JSON, leading to incorrect syntax highlighting. ### CODE FIX 1. **Change File Extension**: - Ensure the file has a `.js` extension. For example, rename `script.json` to `script.js`. 2. **Set Language Mode in VS Code**: - Open the Command Palette (`Ctrl+Shift+P`). - Type "Set Language Mode" and select it. - Choose `JavaScript` from the options. 3. **Associate File with JavaScript**: - Right-click the file in the Explorer. - Select `Open with` > `JavaScript` to set the default language. By following these steps, the code will be correctly recognized and syntax highlighted as JavaScript.
