Zig Control Flow

Use this skill when writing conditional logic, loops, switch expressions, or using Zig's block/defer mechanisms.

When to Use This Skill

• Writing if/else expressions (including with optionals)
• Using switch as an expression
• Writing for and while loops
• Using labeled blocks for early returns
• Understanding defer execution order
• Using unreachable for optimization hints

if

Zig's if is an expression:

const val = if (condition) x else y;
