Study Notes

Blockly Loops

Blockly lacks direct for or while loops.
Create loops using Repeat and Conditional blocks.
Loops can process data like rows in a dataset.
Achieve similar functionality to standard loops using blocks and techniques.

Using the Repeat Block

Drag the "Repeat" block onto the workspace.
Specify the number of repetitions.
Add the code to repeat inside the block.
Drag and drop the "Repeat" block.
Set the count of repetitions.
Add the desired blocks within the loop.

Using a Conditional Loop

Drag a "Conditional" block onto the workspace.
Set the condition for the loop to continue.
Place the repeating code within the "true" branch.
Increment a counter variable to control iterations.
Drag and drop a "Conditional" block.
Set a condition to define loop continuation.
Add the blocks to be repeated within the "true" branch.
Increment a counter variable within the loop to control iterations.

Example: Printing Numbers from 1 to 5

Create a variable named "counter".
Initialize "counter" to 1.
Use a "Conditional" block with the condition "counter < 6".
Inside the true branch:
- Print the value of "counter."
- Increment "counter" for the next iteration (e.g., counter = counter + 1).
Create a variable named "counter" and initialize it to 1.
Use a "Conditional" block with the condition "counter < 6".
In the true branch:
- Print the value of "counter."
- Increment "counter" for the next iteration.
