I successfully built d8.exe from sources

I made a simple JavaScrit file called test.js:

function test( obj ) {

return obj.prop + obj.prop;

}

I ran d8.exe with the command line bellow:

d8 --enable-inspector --shell test.js

I am able to call my test function from the d8 shell interface:

V8 version 7.5.0 (candidate)

d8> test( { prop:'a'} )

"aa"

d8> test( { prop:'ab'} )

"abab"

d8>

Can I, and if so, how, debug test.js from the Chrome Dev Tools?

Does the documentation help? https://v8.dev/docs/inspector

Not really. Too succinct. Not clear what is documented here.

Ok. That was a dumb question. In order to connect CDT to a program embedding V8, that program first has to implement the back-end WebSocket.

Doing that with d8 at a starting point seems a bad idea.
