What are global contexts?

Global contexts are like shared notebooks that everyone uses when they're playing a game together.

Imagine you and your friends are all building a big castle in the sand at the beach. You each have your own little bucket and shovel, but there's also one big notebook that everyone can see and write in. This notebook has special notes about things like what time the tide comes in, or how many blocks tall the tallest tower is. That notebook is like a global context, it helps everyone stay on the same page so the castle stays strong.

If you don’t use the shared notebook, and someone else thinks the tide comes at 10 AM while you think it's 2 PM, your sandcastle might get washed away! But if you all check the global context notebook, you know what to expect, like a map that helps everyone play fair.

Think about when you're on a video call with family. Everyone uses the same screen and hears the same voice, just like how global contexts help computers and apps work together smoothly.
