Scala.js no longer experimental | The Scala Programming Language
Today, we announced the release of Scala.js v0.6.0, the Scala to JavaScript compiler, and dropped the experimental flag associated to it. Yes, you read it right: Scala.js is no longer experimental! After exactly 2 years of development, we finally feel comfortable calling it production-ready. Note, however, that Scala.js is not part of the Typesafe Reactive platform. Thus, although we consider Scal

zipWith (mapping over multiple Seq) in Scala
Suppose I have val foo : Seq[Double] = ... val bar : Seq[Double] = ... and I wish to produce a seq where the baz(i) = foo(i) + bar(i). One way I can think of to do this is val baz : Seq[Double] = (foo.toList zip bar.toList) map ((f: Double, b : Double) => f+b) However, this feels both ugly and inefficient -- I have to convert both seqs to lists (which explodes with lazy lists), create this tempora
Announcing Scala.js 0.5.3
Jul 30, 2014. We are excited to announce the release of Scala.js 0.5.3! This release was focused mostly on performance, bringing speedups from 1.3x to 3.3x to your applications. In some cases, Scala.js becomes slightly faster than JavaScript! Scala.js 0.5.3 is backward binary compatible with older versions of the 0.5.x branch. However, it is not forward binary compatible. This means: You don’t nee

Scala’s abstract override, stackable traits, and object hierarchy linearization
Stackable traits in Scala refers to being able to mix in multiple traits that work together to apply multiple modifications to a method. This involves invoking super.theMethod and modifying its input and/or output. But what is super in the context of a trait? The class (or trait) the trait extends from? The class the trait is being mixed into? It depends! All the mixed in traits and all the superc
