Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Bloomberg invests in Node.js – Shouldn't you?
Bloomberg are currently sponsoring Igalia to work on adding native Decimal number support to JavaScript.
https://github.com/tc39/proposal-decimal
This is an active proposal and was last discussed in the September 2023 meeting.
- Rant - Javascript should be able to do simple f**king math by now
-
Wasmer takes WebAssembly libraries mainstream with WAI
would it be possible, for example, to access the standard decimal library of C# or Python via Javascript, thus not having to wait for the TC39 spec / implementation? [1]

Speeding up the JavaScript ecosystem - one library at a time
There's a BigDecimal TC39 proposal to bring this kind of thing to the native language, but until then you have to choose between accuracy and performance.

Best way to deal with excessive decimal results in calculator
To solve the problem while JavaScript waits on its own BigDecimal API, you can use something like bignumber.js to perform your calculations.

How can i prove that 0.1 + 0.2 = 0.3 is there like a function or ANYTHING i can do to bypass this error which occurs in most programming languages
TC39 is now advancing Built-in decimal datatype in JavaScript.

Integer Math in JavaScript
given the popularity of javascript, it's about time we had better native tools for dealing with numbers in general, but it seems like the discussion is very slow on this front. for instance, the decimal proposal is still at stage 1 [1]. and no, BigInt does not solve that.

Funky problem with the math in my calculator?

WASM by Example
The component model is already shipping in Wasmtime, and will be stable for use in Node.js and in browsers via jco (https://github.com/bytecodealliance/jco) soon. WASI Preview 2 will be done in December or January, giving component model users a stable set of interfaces to use for scheduling, streams, and higher level functionality like stdio, filesystem, sockets, and http on an opt-in basis. You should look at wit-bindgen (https://github.com/bytecodealliance/wit-bindgen) to see some of the languages currently supported, and more that will be mature enough to use very soon (https://github.com/bytecodealliance/componentize-py)
Right now jco will automatically generate the JS glue code which implements a Component Model runtime on top of the JS engine's existing WebAssembly implementation. So, yes, Components are a composition of Wasm Modules and JS code is handling passing values from one module/instance to another. You still get the performance benefits of running computation in Wasm.
One day further down the standardization road, we would like to see Web engines ship a native implementation of the Component Model, which might be able to make certain optimizations that the JS implementation cannot. Until then you can consider jco a polyfill for a native implementation, and it still gives you the power to compose isolated programs written in many languages and run them in many different contexts, including the Web.
(Disclosure: I am co-chair of WASI, Wasmtime maintainer, implemented many parts of WASI/CM)

Spin 2.0 – open-source tool for building and running WASM apps
Thank you!
To your point, the primary consideration for choosing the languages is their support for WebAssembly, and WASI in particular.
Due to Spin's heavy use of WASI and the component model, languages that have first party support in the WIT bindings generator (https://github.com/bytecodealliance/wit-bindgen) are the easiest to implement, followed by languages that can be built on top of the support for those with first party support.
For example, the JavaScript support is built by embedding QuickJS (in particular, Shopify's Javy project — https://github.com/fermyon/spin-js-sdk), which then uses the Rust SDK.

Rust + WASM + Typescript [+ React]
There are many options, but what worked best for me is compiling with cargo-wasi and loading the resulting Wasm file with browser_wasi_shim. Using wasm32-wasi instead of wasm32-unknown-unknown requires a bit more work (the communication with JS has to be set up manually), but gives the flexibility of having just a Wasm file that can be dropped in and loaded dynamically. (There's wit-bindgen for generating wrapping code according to an interface definition but I didn't have much success with it.)

Using WASM for a plugin system in Rust? (generate code at runtime and then hot reloading it as a library)
Yep, you're right. For this, there are a few options. The ones most relevant to you are fp-bindgen, which targets Wasmer, and wit-bindgen, which targets wasmtime.
