How to Build a Choropleth Map in JavaScript
It is needed to link the required JS scripts in the section of the HTML page. These scripts include the Core and Geo Maps modules and the file that contains geodata for the world map, all of which are available on the CDN. I'll also use two more script files to connect the data to the choropleth map. One is the Data Adapter, which will help load the data, and the other is Proj4js, a JavaScript library that will transform the coordinates from one coordinate system to another so the data can be plotted on the map accurately.

[Excel] VBA vs. Office Scripts
E.G. if I wanted to use proj4js apart from copying the entire build file into my source code, there is no easy way for me to use this library. I.E. code reuse is a nightmare still.

How to Build a Connector Map in JS
We need the Core and Geo Map modules to take care of data visualization in the form of a connector map, geodata for a world map, and the Proj4js library to take care of geographic coordinates.

Creating a JS Connector Map to Visualize Tour de France 2021 Route
One more script to wrap up the map-related additions is Proj4js, a JavaScript library that ensures the plotting of coordinates over the appropriate geographical area.

How to Build an Interactive Flow Map in JavaScript
In addition, I will make use of another JavaScript library — Proj4js — which, in short, takes care of plotting the coordinates over the respective geographical areas.

We’re the Microsoft Office Scripts and Power Automate teams – Ask us Anything (and come celebrate Office Scripts GA with us)!
In this way we can also still use javascript libraries to do complex tasks. E.G. Projection which is far too complicated to do in PowerAutomate. I've had this use case when trying to go from Latitude Longitude coords created by a phone to British National Grid coordinate system.

How to read moon projections
Was hoping to make a mosaic of tiles. I used poj4js to convert data points, but it turned out to be very inaccurate for the moon (like off by 20 degrees or more).

Distance between points to polygon/polygon to polygon on a sphere (Earth)
Then see in the doc here : https://github.com/proj4js/proj4js how to convert, it's easy once you have the definition.

WASM_of_OCaml
Yes. Darklang was originally in OCaml using js_of_ocaml, and we ported it to F# using Blazor (https://github.com/darklang/dark/tree/main/backend/src/Wasm). It works.
We found that in dotnet 6, the code was much slower, with long startup times and a much bigger download, than in js_of_ocaml. It also had a lot of issues in running in a Webworker, which wasn't the case for js_of_ocaml.
In dotnet 7, the webworker issues are better and AOT is easier, so startup is faster. Download sizes are still bad, and it's still slower than js_of_ocaml.
However, dotnet allows almost any code to run in WASM, which js_of_ocaml had large limitations. This meant a decent chunk of functionality had to be worked around to make separate js vs native targets, which also was a massive pain and took a long time. Dune's virtual targets wasn't ready at the time - I think we were one of the test cases for it.

It's so unfortunate they decided to go with the Clojure/Haskell type syntax, as opposed to something friendlier like Elixir. A lot of people will not even try this language as a result. [Unison]
Why should I use this instead of https://darklang.com/

Cloud, Why So Difficult?
First it was probably Dark. They made a lot of noise some years ago, but then I never heard of them again (looking at their current website, looks like they moved on to AI now, obviously).

New open-source programming language for DevOps engineers by the creator of the CDK
Reminds me of Darklang. Personally, I don't think vendoring cloud services into a language is going to be beneficial. I'm curious how the language deals with vendor updates. Do I have to upgrade the language then? If so, I see a lot conflicts coming from this. Then it comes down to Javascript or HCL, the HCL bit makes me think that the below statement is not as truthy as it is on the surface:

Darklang Release 9
We still don't have all that many users (~100 active), so I'm not sure you'll find an answer here. But we collect that sort of feedback publicly, which might answer your question: https://github.com/darklang/dark/discussions/categories/feed...

Making Something Waspy: A Review Of Wasp
I wish I could remember what took me to YCombinator's website on the 10th of October, 2022. That was when I first heard about Wasp and another language called DarkLang. After I learned about Wasp, I was intrigued and curious to know how it works, which led me to join the discord server the next day.

The Current State of Infrastructure From Code
There are others in this space I did not assess like Encore, Shuttle, Modal, and Dark. These were not assessed for the sake of time. If you're interested in IfC, I encourage you to take a look at these others.

Finally, we have support for negative numbers!
Oh, finally! I was waiting to build my serverless CRUD webapp in Dark (OCaml + JavaScript and Fsharp?) until they had support for returning negative numbers on a GET request!
