Key Features of D

D

Expressive

Support for multiple programming paradigms, with strong metaprogramming capabilities.

Fast

D programs are compiled, leading to faster execution times than interpreted languages.

Safe

Functions tagged as @safe restrict them to a memory-safe subset of D.

Language Interop

Seamlessly embed C and C++ into your D projects, giving you access to millions of libraries.

Better C

Integrate D into C projects using the -betterC compilation flag.

Optional GC

Leave it enabled when it's needed, and disable it when it's not.

Get mentored the D way

Every language has its own way of doing things. D is no different. Our mentors will help you learn to think like a D developer and how to write idiomatic code in D. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in D - they'll help you discover the things you don't know that you don't know.
