v4 Control Flow

• add: for (init; cond; post)
• add: break; and continue;
• add: && and || (short-circuit)

for loop shape

for (init; cond; post) {
  body
}

• init once
• cond before each iteration
• post after each iteration

break / continue

• break exits nearest loop
• continue skips to next iteration
• both are loop-only

short-circuit logic

• a && b
  • if a is falsey, skip b
• a || b
  • if a is truthy, skip b

Result is a boolean.
