Flipped classroom recap/Q&A

The flipped classroom practice should have trainees

• Evaluate some boolean expression in the REPL
  • true/false literals
  • comparisons with ==
  • comparisons with ===
  • comparisons with <, <=, >, >=
  • logical operations to combine boolean expressions: &&, ||
• Write and run programs using if statements
  • without else clause
  • with else clause
• Write and run programs using while statements
• Some exposure, but maybe not practiced:
  • terminal commands (cd, pwd, )
  • else if

Some questions/prompts that may be useful

• What does this program do? (show programs of varying degrees of complexity using boolean expressions, conditionals and iteration to regulate summing and console.logging)
• What does this expression evaluate to, using boolean expressions?
• What kinds of data types have we seen so far? (without getting too technical, "string", "number", "boolean", maybe "undefined").
• What is the operator that allows us to figure out the type of some data.
• What is the difference between 9 > 8 and 9 > 8 === true
• Why/when do we use conditionals
• Why/when do we use iteration
• Discuss solutions to practice exercises (particularly 3.2 as it asks how many test cases we should write)
