I noted that some sites like this:
https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker (click on install)
can call external program prompting a request.
I remember the use of ActiveXObject years ago but now it is not supported in my chrome browser.
How can these sites call external program with javascript? Is it possible to call a program without the prompt?

When you click on the button to install the plugin, it is calling vscode:extension/streetsidesoftware.code-spell-checker
It is using a registered URI scheme which your application is able to handle. How to register it really depends on what your application is written in.
