Good lord we got hit with the “only approved for at risk groups” line while trying to get a COVID booster. Friendly reminder that being overweight makes you qualify for it (my BMI is finally leading to positive health outcomes).

Yatsi can compile and evaluate functional closures now, and you can watch in the closure visualizer: yatsi.dev/closures/ It's still tailored to my own perspective on what's interesting. Gonna build a lot of these playgrounds until I figure out what's more useful for other people

Yatsi can finally return values from functions. And recursion just sort of works out of the box (I do have to add some call stack limits just in case): No real closures yet. Once I add that, I'll start working on some fun visualizations for how that all works under the hood.
An image of the Yatsi TypeScript interpreter playground, showing correct output for some console.log functions and a fibonacci calculation function to demonstrate return values, arguments, and recursion.

Yatsi can run parameter-less functions that return `undefined` now:
A screen shot showing some TypeScript code that calls a function which calls console log. The source has the function body, and we see an expected output, with a status of "PASS" in the corner.
