Industrial Note

D is used in performance-critical applications, game engines, high-performance computing, and financial software requiring fast, reliable code.

Quick Explain

• ▸D supports imperative, object-oriented, and functional programming paradigms.
• ▸It offers safe systems-level programming with modern abstractions.
• ▸Templates, mixins, and compile-time reflection enable advanced metaprogramming.

Core Features

• ▸Strong static typing with type inference
• ▸Modules and package system
• ▸Function overloading, operator overloading
• ▸First-class functions and closures
• ▸Compile-time reflection and code generation

Learning Path

• ▸Learn basic syntax and control flow
• ▸Understand structs, classes, and interfaces
• ▸Explore templates and ranges
• ▸Practice compile-time reflection and mixins
• ▸Build real-world applications with Dub

Practical Examples

• ▸Hello world CLI
• ▸Range-based iteration example
• ▸Template function for generic containers
• ▸Class with inheritance and interfaces
• ▸Compile-time mixin code generation

Comparisons

• ▸Similar performance to C++
• ▸Higher-level features than C/C++
• ▸Easier syntax than C++ templates
• ▸Smaller ecosystem than Rust or Go
• ▸Better compile-time metaprogramming than most mainstream languages

Strengths

• ▸High-performance native code
• ▸Clean modern syntax with C-style familiarity
• ▸Powerful compile-time metaprogramming
• ▸Versatile multi-paradigm language
• ▸Rich standard library with ranges and algorithms

Limitations

• ▸Smaller community and ecosystem than C++ or Rust
• ▸Less industrial adoption for large-scale projects
• ▸Limited GUI library support
• ▸Garbage collector can be unpredictable in real-time systems
• ▸Interfacing with C++ can be complex

When NOT to Use

• ▸Large-scale GUI-heavy desktop applications
• ▸Projects needing massive library ecosystems
• ▸Embedded systems with strict real-time constraints
• ▸Rapid prototyping with minimal setup
• ▸Applications requiring maximum portability with minimal compilation

Cheat Sheet

• ▸import std.stdio;
• ▸int x = 10;
• ▸void main() { writeln("Hello World"); }
• ▸struct S { int a; }
• ▸template mixinExample() { ... }

FAQ
