Empty

Open DrakonTech with a blank workspace, ready for your ideas

Functions

A complete list of DRAKON's algorithmic constructs, including the silhouette. Importing and exporting functions. Module-level variables, async and await. Basic algorithms, including Hello world, Fibonacci, and FizzBuzz.

Classes

Object-oriented programming with light-weight classes that do not use the keywords “class”, “new”, and “this.”

State machines

State machines, or finite automata, represented with drakon flowcharts.

Algo-props

Backward chaining implemented with algorithmic properties, or algo-props. Algo-props make your programs shorter and simpler by reducing binding. With backward chaining, one does not call functions explicitly but simply uses data when needed.

Class algo-props

Algo-props that are defined at the class level.

Lift: a state machine demo
