Proposal: Signals as a Built-In Primitive of JavaScript
I have to admit: you're perfectly right here. React of course always relied on mutable state in it's implementation β just so we don't have to. I derailed a lot here to keep this funny thread going ;) I'm still not with you on your definition of "functional", since you treated it synonymously with "purely functional". Functional means just made by applying and composing functions, and react UI is created exactly like that. There is an awesome algebraic effects proposal[1], which will hopefully will be added to JavaScript one day, then react will make use of it to become purely functional.

Letlang, a programming language targetting Rust - Road to v0.1
Super interesting, there is a proposal to add this to JavaScript and several languages that use this, unison, koka & eff. I had no idea this was even a thing!

Go Replaces Interface{} with 'Any'
Ok I was wrongly assuming that panic was expecting an error type, in fact it's an interface{}.
> Your use of exceptions for flow control (i.e. goto) is considered harmful
Exceptions are a way to delegate error handling to the caller by giving them informations about the unexpected behavior. It implies that the expected behavior is the "happy path" (everything went well) and any deviations (errors) is unexpected.
This is far from a goto because you can have `try/finally` blocks without catch (or defer in golang).
Also, exceptions are just a kind of algebraic effects that do not resume. There was a proposal to JS for this: https://github.com/macabeus/js-proposal-algebraic-effects
This is also easier to test. assertRaises(ErrorType, func() { code... })
Almost every Go library I've seen just return an error (which is just a string), you'd need to parse it to assert that the correct error is returned in special conditions.

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

GopherJS now supports Go 1.18! π₯³
Release notes have all the details. For now it is just compatibility with the 1.18 standard library, but generics support is planned.

Is there a game engine in Go that can make an RTS game?
Why not use https://github.com/gopherjs/gopherjs with jMonkeyEngine as-is?

my experience with blazor
When I wrote my first project in this year, I don't even planed to used blazor. But my childlike curiosity directed me on that path. I wanted to know, haw hard will be port game from desktop to web browser in .net. And I found out is not that hard. But I have experience with similar tools before. I used gopherjs and emscripten. Thanks to that I know what must to do, to communicate c# with javasrcipt. I made working blazor port pretty fast. Not only server side but webassembly to. Of curs create port for different platform always generate some problems. Most weird problem I have in blazor is how floating point number behave. I received in some cases NaN values. This problem I resolve adding value like 0.0001 in calculation.

Replace JS with Rust on front-end, possible? Advisable?
If you're already building the backend in go and you don't like the prospect of coding in JavaScript it might be worth trying out https://github.com/gopherjs/gopherjs

Has anyone created a dApp that interacts with browser wallets?
Maybe this is were https://github.com/gopherjs/gopherjs will truly shine? Has anyone ever seen Go used for this?

Is it wise to build ecommerce website with golang?
You can also write JS in Go with GopherJS, but if you don't fully understand the underlying JS webdev ecosystem, adding this extra layer of complexity is probably a really bad idea, at least at first.
