Hello @Gen Pir ,
Thank you for taking time to post this issue in Microsoft Q&A forum.
Looks like IntelliSense doesn’t show all the file types, but .js file should be shown correctly.
I don’t think a jsconfig.json file can change the IntelliSense to show all the file types. I would suggest you submit a feedback ticket on our Developer Community – Visual Studio.
Besides, please kindly check if any VS extensions meet your requirements, from VS Marketplace.
Thanks for your understanding, have a nice day.
Kind Regards,
Tianyu
