About D

module helloworld;

import std.format;

string hello(const char[] s = "World") {
    return format("Hello, %s!", s);
}

D is a systems programming language with C-like syntax and static typing. It combines efficiency, control and modeling power with safety and programmer productivity. The language was developed originally by [Walter Bright] (https://en.wikipedia.org/wiki/Walter_Bright) and Andrei Alexandrescu since D version 2.

D is the culmination of decades of experience implementing compilers for many diverse languages and has a large number of unique features:

  • high level constructs for great modeling power
  • high performance, compiled language
  • static typing
  • evolution of C++ (without the mistakes)
  • direct interface to the operating system API's and hardware
  • blazingly fast compile-times
  • allow memory-safe programming (SafeD)
  • maintainable, easy to understand code.
  • short learning curve (C-like syntax, similar to Java and others)
  • compatible with C application binary interface
  • multi-paradigm (imperative, structured, object oriented, generic, functional programming purity, and even assembly)
  • built-in error prevention (contracts, unittests)

The D Language Foundation is the organization devoted to developing and advancing the D language.

Exercism is a great website

The reviews are incredibly helpful because they help me see things that I missed, learn about new ways and sometimes interesting discussions that can add a fun twist to maybe a simple problem.

Fun. Challenging. Interesting
