Basic Syntax

const std = @import("std");

pub fn main() !void {
    const stdout = std.io.getStdOut().writer();
    try stdout.print("Hello, {s}!\n", .{"World"});
}

// Function with error handling
fn divide(a: f32, b: f32) !f32 {
    if (b == 0) return error.DivisionByZero;
    return a / b;
}

// Compile-time execution
fn fibonacci(n: u32) u32 {
    if (n <= 1) return n;
    return fibonacci(n - 1) + fibonacci(n - 2);
}

const fib10 = comptime fibonacci(10);

Memory Management

Error Handling

const FileError = error{
    AccessDenied,
    FileNotFound,
};

fn openFile(path: []const u8) FileError!File {
    // Implementation
}

// Using catch
const file = openFile("test.txt") catch |err| {
    std.debug.print("Error: {}\n", .{err});
    return err;
};

// Using try
const file2 = try openFile("test.txt");

Best Practices

• Use defer for cleanup (like Go)
• Leverage compile-time execution
• Explicit error handling with try/catch
• No hidden control flow or allocations
