This is super cool. I absolutely agree with Steven that we have a 
*lot* to go (in terms of compiler diagnostics, and really, 
general user experience), but it’s always great to hear about the 
wisdom of D being spread around.

I’ve mentioned it on the discord, but I’d perhaps be open to 
chipping in some for these improved diagnostics / UX improvements 
(number one on my wishlist is improved code completion engine 
using the DMD front-end!). I really think those are the two 
biggest things that are holding adoption back now, and we still 
have a lot of work in that regard. This is actually where I think 
Rust has a leg up on us — the language might not be that great, 
but you *really* can’t beat those compiler diagnostics.

Does the site crash e.g. with an error code or does the browser crash? 
More information may help debug it.

Many times, it is estimated that a `JS` is too large to load.
Not only did `the browser` crash, but even the `computer` crashed.
Mine is `32-bit, 2G` computer.

What OS and Browser?

I just tested on an old 32 bit machine with 2GB of RAM and both 
Chrome and Firefox worked normally.

On Chrome I see there are some errors in some scripts though:

Uncaught ReferenceError: jQuery is not defined navigation.js:55
Uncaught ReferenceError: jQuery is not defined select2.min.js:21
Uncaught TypeError: Cannot read property 'fn' of undefined 
mivhak.min.js:1

But even with these errors it load normally.

Finally in both browsers I use only one extension: ublock origin, 
which blocked some trackers from twitter, facebook.

And on Firefox it indeed almost freezes for a like 2 seconds, and 
occurs with the status bar showing: "Read c0.wp.com", after that 
the page finished loading.

I tried it just before, no problem last time.
Then, I tried again here. It's circling all the time. You can't 
see the `source code`,
`F12` can't either.
`chrome/edge/windows10`. I don't know why.

I agree about the bad error message with missing semicolons. 
Looks like it inspired improvement!

 I have read that Visual D has a better debugging experience, 
 but I need dub support for these projects, and Visual D focuses 
 on Visual Studio integration, something I don’t necessarily 
 want to deal with in teaching these kids


This is truly an understatement about Visual D, the debugging 
experience is at par with the native C++ one in VS. If I was a 
kid from that group, I would feel tormented by the dub/vscode 
experience :) Rainer Schuetze deserves a statue.

Thanks, but no statue please ;-) BTW: the mago debug engine was 
originally written by Aldo Nunez. I adopted it and made it work as an 
extension to the VS Concord debugger.

Please note that the native debug engine for VS Code is the same as for 
Visual Studio, and it only took some changes to make the former load 
extensions, too: 
https://github.com/microsoft/vscode-cpptools/issues/2932#issuecomment-853774543

Integrating it with code-d is just some installation issues away, see
