Common Components

Common Components is a core part of How To. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding common components well means you can read other people's How To code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

What common components means in the context of How To
A minimal example you can run or read in the playground on the right
A common mistake to avoid when working with common components
