Operators, Functions, and Properties – part 29
In this series, we’ve been looking at simple machines where pushing a button invokes an operator that changes the state of the machine. Stopwatches, coffee makers, calculators are all examples of such machines – some simpler than others. Many of … Continue reading

Operators, Functions, and Properties – part 28
The prior post in this series showed that we can get complex and rich behavior from combining simple operators and feeding their output back to their input (through what is called “state”, and the whole arrangement is known as a … Continue reading

Operators, Functions, and Properties – part 27
In the last installment in this series, we showed a state machine that produced powers of two while keeping track of which power of two it was. Each time you press “next” the next power of two is produced. (the … Continue reading
