Loops Practice

​While Loops Practice

• Simple console.log levels to practice using while loops.

  • Level 1: Use a while loop to print the numbers 0-99

  • Level 2: Use a while loop to print a message 100 times

  • Level 3: Use a while loop to fill an array and print the results

  • Level 4: Complete BOTH choice levels

For Loops Practice

• Simple console.log levels to practice using for loops.

  • Level 5: Use a for loop to print the numbers 0-99

  • Level 6: Use a for loop to print a message 100 times

  • Level 7: Use a for loop to fill an array and print the results

Open Ended

Choose a loop from any of the modules you just completed. Identify the number of times the body of your iteration statement will execute. Describe a condition or error that would cause your iteration statement to not terminate and cause an infinite loop. If no such condition or error exists, explain how the loop could be modified to cause an infinite loop.

Loops and Screen Elements

• Practice writing programs that modify screen elements with loops

• Screen elements have already been designed to have repeated patterns (e.g. "dice0", "dice1", "dice2" ...) that make it possible to write code that modifies every screen element

  • Level 8: Simple introduction to using loops to generate a sentence with random font colors and font sizes

  • Level 9: Update a Dice Roller app that has some working functionality already

  • All of the different concepts you'll need to use are already in the starter code of this app, but you'll need to think through how to put them together to get the target code behavior

Open Ended

Write about a bug you found during your work in class. Describe the problem, how you discovered it, and what changes you made to fix the issue.
