Core Concepts of zig intermediate

Production-ready compilation flags and build commands

Comptime: Generic Programming

Type-level metaprogramming with comptime parameters. See Zig intermediate comptime examples below

⚠️ Common Error

Using runtime values in comptime

✓ Solution

comptime fn generic(comptime T: type, comptime size: usize)

+450%

Optimization: Inline Loops

Unrolled loops at comptime for maximum performance

+320%

Zig intermediate comptime examples: Async/Await

Evented I/O with suspend/resume model

5x faster

Best practices: Custom Allocators

Arena, FixedBuffer, PageAllocator patterns

⚠️ Common Error

Global allocator leaks

✓ Solution

var arena = std.heap.ArenaAllocator.init(allocator);
