Types in Depth

Types in Depth

In this lesson — part of Data Deep Dive — you'll learn types in depth in Cairo and why it matters in real work.

Why it matters

Types tell you what operations make sense and catch whole classes of bugs early.

Key ideas

• Common types: text, numbers, booleans
• Type conversion and coercion
• When to be explicit about types
• Type errors and how to read them

In practice

Here's the idea in pseudocode — the exact syntax varies by language:

// Cairo: values have types
count = 3        // number
label = "items"  // text
ready = true     // boolean

Try it yourself

Exercise: In Cairo, convert a number to text and back, and print both.
