 Marlowe is written as a Haskell data type, and thus it is straightforward to generate Marlowe smart contracts using Haskell. Nevertheless, we also provide a library written in TypeScript that can be used to generate Marlowe smart contracts from TypeScript or JavaScript in a similar way to how one would by using Haskell. If you are not familiar with TypeScript, you can also use the API as if it was written in JavaScript since TypeScript is a superset of JavaScript.

 It is this final value that is converted to pure Marlowe with the *Compile* button (in the top RH corner). If compilation is successful, the compiled code is shown in an overlay (which can be minimised):

 On successful compilation the result can be sent to the simulator using the *Send to Simulator*  
 button in the top RH corner of the page.
 
 If the contract cannot successfully be converted to Marlowe, the errors are also shown in overlay:
