Now that web assembly has arrived, C++ is a perfectly suitable 
language for the browser.  I'm predicting Javascript will become 
a legacy language for the web in 5 years.

I recently wrote 2 applications in C# web assembly (using Blazor) 
and they probably took me 20% of the time had I needed to write a 
backend in C# and a frontend in Javascript.  It was an awesome, 
eye-opening experience, and I'm never going back.

There may still be a need for Javascript for a few things, but 
not many.  Javascript's days are numbered.  IMO, C#, C++, Rust, 
and other general purpose languages that can compile to web 
assembly is where it's at for the future of the web.  And, I 
don't see why D can't be a major player there, as I know it 
already has been demonstrated to be:
