Now there have been some changes, so I will write a new answer.
If you use wasm, then there are two ways:
1. Really drag the entire runtime (mono) and dlls to the front
2. AOT compilation of all code at once in wasm - this appeared in .NET 6. In this case, neither dlls nor runtime no need to drag.
In the case of F#, there is another way - Fable.
When using Fable, F# will be transpiled to JS. Naturally, in this case, heaps of libraries will not be available.
