Scratch-project: https://scratch.mit.edu/projects/520880966/
This program uses the scratch-api module for interfacing with Scratch and the wikijs module to interface with Wikipedia.
In the Scratch project, user input is converted into numbers, and converted back into string in the Node.js-code. This is because Scratch's cloud variables cannot be used to store letters.
The program then takes the user input and uses that as a keyword for the Wikipedia API. It then returns a summary (basically the first paragraph) of the page and uses string splitting to display as much of the text as possible in the Scratch side, without ending the sentence without a period.
The text is then converted into numbers, split into 4 different input variables and joined together in Scratch. It's then converted back to letters and displayed in the cat's text bubble.
