With its unique blend of features, D empowers developers to create high-quality software applications.

Safe and efficient

The D programming language prioritizes safety and efficiency, enabling developers to create robust and high-performance applications.

Memory safety: D eliminates entire classes of bugs by enforcing memory safety. It utilizes a garbage collector to automatically manage memory allocation and deallocation, preventing memory leaks and dangling pointers. Additionally, D’s strong type system and compile-time checks help catch errors early, reducing the risk of runtime exceptions.

High performance: D is designed for speed. It compiles to native code, producing executables that run efficiently on a wide range of platforms. D’s syntax is expressive and concise, allowing developers to write code that is both readable and performant.

Concurrency and parallelism: D excels in developing concurrent and parallel applications. It provides built-in support for multithreading and offers various synchronization primitives, making it easy to write scalable and responsive software.

Resource management: D’s resource management features, such as RAII (Resource Acquisition Is Initialization), help developers manage resources efficiently and avoid memory leaks. RAII ensures that resources are automatically acquired and released when no longer needed.

The combination of safety features, high performance, and resource management makes D an excellent choice for developing mission-critical applications and systems software.

High performance

D’s high performance is attributed to several factors, including its efficient compiler, expressive syntax, and support for various optimization techniques.

  • Native compilation:

    D compiles directly to native code, producing executables that run at high speeds. This eliminates the overhead associated with virtual machines or intermediate code layers.

Expressive syntax:

D’s expressive syntax allows developers to write concise and readable code. The compiler can perform aggressive optimizations on this code, resulting in efficient machine instructions.

Zero-overhead abstractions:

D provides zero-overhead abstractions for common programming tasks, such as arrays, strings, and delegates. These abstractions are implemented efficiently in the compiler, avoiding the performance penalties often associated with high-level features.

Support for parallelism:

D’s built-in support for multithreading and parallelism enables developers to write scalable and responsive applications. The language offers various synchronization primitives and data structures designed for concurrent programming, allowing efficient utilization of multiple cores and processors.

The combination of these factors makes D an excellent choice for developing high-performance applications, such as games, operating systems, and scientific simulations.

Expressive syntax

D’s expressive syntax is one of its defining features, enabling developers to write code that is both concise and readable. This expressiveness contributes to the language’s high performance and maintainability.

Operator overloading: D allows operators to be overloaded for user-defined types, providing a natural and intuitive way to work with custom data structures. This feature enhances code readability and reduces the need for verbose and error-prone workarounds.

Templates: D’s powerful template system enables generic programming, allowing developers to write code that can be reused for different data types. Templates improve code maintainability by eliminating the need for duplicate code and reducing the risk of errors.

Delegates and lambdas: D provides delegates and lambdas, which are powerful tools for creating anonymous functions. These features promote functional programming techniques, making code more concise, expressive, and easier to understand.

Range-based for loops: D’s range-based for loops simplify the iteration over collections and arrays. This feature makes code more readable and reduces the risk of off-by-one errors.

D’s expressive syntax empowers developers to write code that is both efficient and maintainable. It enhances productivity, reduces development time, and improves the overall quality of software.

Powerful metaprogramming

Metaprogramming is a powerful technique that allows programs to manipulate their own source code or structure at runtime. D provides extensive support for metaprogramming, enabling developers to write code that generates, inspects, and modifies other code.

Macros: D’s macros are a versatile tool for metaprogramming. They allow developers to define custom syntax and generate code dynamically. Macros can be used for a wide range of tasks, such as code generation, refactoring, and creating DSLs (Domain-Specific Languages).

Templates: D’s templates are another powerful metaprogramming feature. Templates enable generic programming, allowing developers to write code that can be used for different data types or algorithms. Templates can be instantiated multiple times with different arguments, generating specialized code for each case.

Reflection: D provides reflection capabilities that allow programs to inspect and modify their own types, methods, and properties at runtime. This information can be used for a variety of purposes, such as generating documentation, debugging, and dynamic code generation.

Code generation: D’s metaprogramming features make it an excellent choice for code generation tasks. Developers can write programs that generate source code for other languages, create custom build systems, or perform code optimization.

D’s powerful metaprogramming capabilities empower developers to write flexible and adaptable software. It enables the creation of sophisticated tools and libraries that would be difficult or impossible to implement in other languages.


D is designed to be a cross-platform language, allowing developers to write code that can run on multiple operating systems and architectures. This portability makes D an excellent choice for developing software that needs to be deployed on a variety of platforms.

Native compilation: D compiles directly to native code, producing executables that run efficiently on the target platform. This eliminates the need for a virtual machine or intermediate code layer, ensuring that D programs perform well on different systems.

Standard library: D’s standard library provides a comprehensive set of cross-platform APIs, covering a wide range of tasks, such as file I/O, networking, graphics, and multithreading. This consistency simplifies the development of portable applications and reduces the need for platform-specific code.

Community support: The D community is actively involved in porting the language to new platforms and architectures. This means that D is constantly expanding its reach and becoming more accessible to developers worldwide.

D’s cross-platform capabilities make it an ideal choice for developing software that needs to run on multiple operating systems, devices, or architectures. It enables developers to write code once and deploy it everywhere, saving time and resources.

Open source

D is an open-source programming language, which means that its source code is freely available to anyone. This openness provides numerous benefits to developers and the community as a whole.

  • Transparency and collaboration:

    The open-source nature of D promotes transparency and collaboration among developers. Anyone can inspect the source code, contribute bug fixes and improvements, and suggest new features. This collaborative approach leads to a higher quality and more robust language.

Customization and extensibility:

Open-source software allows developers to customize and extend the language to suit their specific needs. They can modify the compiler, create new libraries and tools, and integrate D with other technologies. This flexibility makes D an attractive choice for developers who require a language that can adapt to their unique requirements.

Security and reliability:

Open-source software undergoes rigorous scrutiny by the community, which helps identify and fix security vulnerabilities and bugs. This collaborative effort results in a more secure and reliable language that developers can trust for their projects.

Community and support:

The open-source community surrounding D is active and supportive. Developers can easily find help and resources online, participate in discussions, and contribute to the project. This strong community fosters a sense of belonging and encourages developers to contribute to the growth and success of the language.

D’s open-source nature makes it a vibrant and evolving language that benefits from the contributions and feedback of a global community of developers.
