Documenting Code in Zig

Just like a map guides you through a new city, good documentation guides you through your code.

Writing Comments

Comments are like notes you leave for yourself and others in your code. They explain what’s happening in plain language.

// This function calculates the area of a rectangle.
fn calculateArea(length: i32, width: i32) i32 {
    return length * width;
}

Imagine you’re a tour guide in a new city. What kind of signs or instructions would you leave for your tourists?

Generating Documentation

Generating Documentation is like creating a travel guide for your code. It provides a clear map for anyone who wants to explore your project.

If you were writing a guidebook for a magical forest, what kind of details would you include to help travelers navigate safely?

Let’s try adding comments and generating documentation for our code. What kind of instructions and guides would you like to leave for your fellow programmers?
