D For A Web Developer

[James via Digitalmars-d]

I have a friend that is a web developer. I, however want to 
collaborate with him, so I am trying to get him to learn D. I  
don't know how to persuade him! How can D be used to greatly 
assist an HTML5/JavaScript web developer? I decided to go here to 
get some good answers. How can D be used to interopt with modern 
web development?
