What is WDL?

If you’re a computer science student, you’ll already know what a state machine is. If you skipped those lectures (I certainly did - Who sits for a Theory Of Computation lecture), worry not, it’s a very simple concept to understand.

Think of state machines as flowcharts with some Inputs, Steps and State.

For example, a state machine to get two numbers from the user and handle for errors could be represented as:

State Machines are powerful because:

• We can use them to represent any form of user interaction, processing, external API calls etc.
