I have been playing with Observable for a few months now, and it is the programming environment of my dreams. There have been many times in the past I wish I could preview the results of a computation when tuning parameters or data, and this allows me to do it and without restricting my expressiveness or domain. Note: I am predominately thinking of graphical and data exploration use cases. An example where I think observablehq has allowed me to go beyond the status quo is my port of Wave Function Collapse https://beta.observablehq.com/@tomlarkworthy/wave-function-collapse https://beta.observablehq.com/@tomlarkworthy/wave-function-c... (early stages). I added the ability to mask individual tiles in the tilesets dynamically and the effect on the generated images is non-intuitive but very satisfying. Manually editing the tilesets in XML which is what the original requires would be too laborious, so its a domain where observablehq really shines. I have more work to make it truly idiomatic of observablehq but the sign that its a genuine force multiplier is there.
