Le radoteur: a script to invent new words.

radoteur.ts

// Inspired by Le Radoteur, invented by Roland Moreno and described in La theorie du bordel ambiant
// Replace the content of input with whatever words you want to use as inspiration and run it with typescript from the command line. Only caveat, it works better if all the input is in the same language.
// The longer the input, the better the output that will appear in the console
