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.
