Blocks and workspace editing

Code Lab becomes easier once you treat the workspace as a construction area, not just a place to press Run.

What the center workspace is for

The main workspace is where you assemble the blocks that represent your program logic.

Use it to:

• place new blocks
• connect related blocks
• rearrange logic visually
• remove blocks you no longer need

A good first editing routine

1. Open Code Lab after signing in.
2. Start with a simple blank area or load a beginner template.
3. Add or inspect a small number of blocks first.
4. Rearrange the layout until the flow is easy to read.
5. Only then think about running the program.

What to pay attention to

While editing, keep checking:

• whether the block order is readable
• whether connected blocks express one clear idea
• whether the workspace is getting too crowded

If the canvas feels messy, execution will feel harder to understand too.

Language note

Code Lab supports both:

• JavaScript
• Python

Choose one language before you get deep into a workspace so you do not confuse yourself during the first session.

Good beginner habit

Make one small meaningful change at a time. In Code Lab, tiny edits are easier to test and easier to explain to yourself after the run finishes.
