sbt is not the only build tool that supports Scala.js. I at least know of support for Maven [1], Pants [2], Gradle [3] (a bit outdated that one, but an interested person could revive it), and there seems to be a path forward for Bazel [4].

scalac is only slow when it needs to compile an entire project. But the Scala tooling ecosystem has invested a lot in incremental compilation, which means that most of the time when you make a change, only 1 or 2 files are recompiled, whi

There is a significant difference between CLJS and Scala.js regarding their use of GCC (Google Closure Compiler). In ClojureScript, GCC is a user-visible feature of the toolchain, so users are encouraged to use GCC-compatible libraries and

Yes once you're at 90 KB the slope will be much less. It will simply grow with the actual code of your app.

The bare minimum for a hello world is 6 KB (before gzip). But of course as soon as you start using Scala collections, it's getting bigger. The minimum for a realistic application is 90 KB (before gzip). That's less than your typ

It's exactly like TypeScript. You write type definitions or you find them online, like in TypeScript, then you can call any JavaScript API using the relevant types. Full relevant docs at https://www.scala-js.org/doc&#x2

In French, and more specifically French as spoken in some areas in Switzerland, there is a very natural way of pronouncing hex numbers: 1 to F are the normal 'un' to 'quinze'. A is 'dix'. 10 is 'seize&#x27

It's always important to put things into context. If you're developing a hello world or a few animations for your mostly static web site, the initial "tax" of Scala.js will always be too heavy. It's not so much the

Wasm will not influence Scala.js' semantics. Scala.js "folding back into Scala" would be a regression as far as development for JavaScript platforms goes. Scala without Scala.js means a Scala that cannot interact with its env

I've implemented support in the Scala.js compiler to emit Longs (64-bit signed integers) as BigInts about 6 weeks ago. [1] Unfortunately, without specific optimizations that are not part of the baseline currently implemented in V8, thi

Nope, nothing to do with surrogates either. Surrogates are code points encoded with 2 code units of 2 bytes each. A number of emoji, like the heart, are coded using multiple code points , which is even more bizarre.

Maybe, but at what cost? I wouldn't be surprised if the cost of verifying the machine code was higher than the cost of compiling wasm to machine code.

I understand all that. I have been writing compilers for more than 10 years, including the compiler of Scala.js. I am not criticizing wasm nor its benefits. What I profoundly dislike is that such good articles about wasm, written by excelle

asm.js was not a well-behaved subset of JavaScript. It was a well-behaved subset of assembly that happened to be encoded in JavaScript. There is virtually no human-written JS code that is amenable to compilation to wasm in a meaningful way.

I can't tell whether you're being sarcastic or not, so I will answer as if you are not. Yes, it is absurd. Because your wasm that was compiled from JS needs to embed an entire implementation of the dynamic nature of JS. And to mak

That would assume you trust the server not to give you malicious machine code (which you of course cannot!). wasm is specified in such a way that it is still sandboxed by the VM that compiles it. If you fetch arbitrary machine code, you can
