- Zig is described as a revolutionary programming language, offering a new way to write programs beyond just replacing C or C++.
- The Zig compiler's ability to compile C code and cross-compile for different architectures is highlighted as a unique and impactful feature.
- Installation of the Zig compiler is straightforward, with detailed steps provided for Windows, including setting environment variables.
- Zig's variable declaration syntax is explained, emphasizing type inference and the use of `pub` for accessibility.
- The article introduces Zig's anonymous struct literals and struct declarations, showcasing their use in initializing structures.
- Bitfields and pointers in Zig are discussed, with examples showing how to declare and manipulate them.
- Zig's array initialization and manipulation are covered, including the use of loops and pointer arithmetic.
- The article explains how Zig can execute code at compile time, using examples like array initialization with labelled breaks.
- Functions in Zig are static by default, with `pub` making them accessible outside their file. The concept of inlining functions is introduced.
- Structs can have functions in Zig, with examples provided for implementing a stack, including constructor and method definitions.
- Building executable programs in Zig requires a `main` function, with commands provided for compilation.
- Zig's test blocks allow for independent testing of modules without needing an executable, showcasing a practical example.
- Debugging in Zig is simplified with `@breakpoint()`, allowing for variable inspection without bloating the executable with debug symbols.
- Low-level programming features in Zig are explored, including bit manipulation for Sudoku grid validation and error handling.
- The article concludes by emphasizing Zig's robustness, performance, and unique features like compile-time execution, comparing it favorably to interpreted languages.
