Mission briefing
Before You Study (5 mins)
Lesson focus: Whether it's a tweet, a bank balance, or a weather report, almost ALL data on the internet travels in one format: JSON. If you can read JSON, you can read the internet's mind.
What you should have ready:
- Your code editor open
- A text file ready to be typed
Quick Concepts
| Term | Simple Meaning |
|---|---|
| JSON | JavaScript Object Notation (Data format) |
| Key | The label (e.g., "Name") |
| Value | The data (e.g., "Divyanshu") |
| Array | A list of things (like a grocery list) |
Think About
Before studying, consider:
- How does Spotify send a playlist to your phone? It sends a list of song titles, artists, and links. That list is JSON.
- It looks like this:
{ "song": "Hello", "artist": "Adele" }
By the End
After this lesson, you'll:
- ✅ Read and write JSON fluently
- ✅ Create a
config.jsonfile for your game - ✅ Change your game settings without touching the code!
