Computers & Developers

Explore how Computers and Developers read the same code in different ways.

---

Prep Work

• Look through Suggested Study
  • What is Programming?
  • What is JavaScript?
• Play compute-it through level 15
• Install (and/or update) Study Lenses - see the Setting Up section
• Go through the ../../0-study-lenses guide so you're ready for class
• Learn a little about variables:
  • (study your favorites of all these)
  • They're like boxes
  • JS Fundamentals - Variables
  • JS Variables
  • JavaScript Variables and Constants

---

Learning Objectives

• 🥚 Code Audiences: You can explain how a single file of code is understood by:
  • Computers: A computer follows the code's instructions one step at a time.
  • Developers: A developer reads the code, comments and variable names to understand what the code is intended to do.
• 🐣 Tracing Variables: You can follow a program's instructions like the computer does, filling out a trace table and checking your work with the [trace] button.

During Class

The most important objective for today is that you learn how to trace variables the way a computer interprets them. If you don't understand this the rest of JS will be a mystery!

Before Break

• All Together:
  • Discuss the diagram with source code, developers and computer
  • Discuss where you can write & run JavaScript
  • Study the tracing-variables examples all together on a coach's screen
    • Demonstrate different study techniques and lenses
• In Small Groups:
  • Study examples 4 & 5 again with your classmates
  • Begin tracing-variables/exercises

Break!

After Break

• In Small Groups:
  • Continue studying tracing-variables/exercises
• All Together Regroup with ~30 minutes left at the end of class for each group to present:
  • what went well?
  • what went less well?
  • lessons learned

After Class

No deliverables. Just lots of study time, alone and in groups. Here's some ideas for what to focus on:

• 🥚 compute-it (all of it), 🐣 little-dot
• Continue studying your favorite online tutorials
• Finish /1-what-is-programming and study as much as you can from /2-just-enough-javascript
• /0-flashcards: ~20 minutes every day (add more cards as you go!)
