ECMAScript, the standard specification underlying JavaScript, is on track for a new release, likely in June.

So far, two proposals have been finalized for inclusion in the ECMAScript 2018 specification. Both are considered as fairly foundational work and not major features, said Zibi Braniecki, a senior software engineer at Mozilla who participates in the development of ECMAScript.

The two proposals include:

  • Lifting of the template literal restriction, to enable the embedding of languages, including domain-specific languages (DSLs). Currently, restrictions on

Ruby, one of the more venerable dynamic languages, has just gained in performance with the new 2.5 release.

Arriving on Christmas Day 2017, Ruby 2.5.0 is the first stable release in the 2.5 series.

New performance features in Ruby 2.5

It boosts performance by 5 to 10 percent by removing trace instructions from bytecode that has been found to be overhead. A dynamic instrumentation technique is used instead. Also, block passing by a block parameter has been made three … Read the rest

For programming languages, languages like Java and Kotlin garnering a lot of attention in enterprise and mobile development in 2017. The JavaScript ecosystem, critical to web development, continued to expand as well.

Overall, the year presented a mixed bag of improvements to both long-established and newer languages.

Developers followed a soap opera over Java, with major disagreements over a modularization plan for standard Java and, in a surprising twist, Oracle washing its hands of the Java EE enterprise variantRead the rest

Groovy, the veteran language for the Java virtual machine, has several enhancements on its roadmap, such as to support Java 9 modularity and Java 8 lambda capabilities. Although closely linked to Java, Groovy offers additional capabilities such as the ability to write compile-time transformations and macros.

The Apache Software Foundation plans the following Groovy upgrades in the next year:

  • Versions 2.5, due in early 2018 for Java 7 and later.
  • Version 2.6 and 3.0, both set to arrive in about

Kotlin, the statically typed alterative Java language for JVM and Android development, is showing signs of making it into the big leagues, getting support in development frameworks.

For example, the Spring Framework now supports Kotlin. And there are new frameworks such as Javalin and Ktor that support Kotlin.

Kotlin frameworks: Support in the Spring Framework

Best known as a venerable Java framework featuring dependency injection, Pivotal’s Spring Framework gained Kotlin support in the Spring 5.0 version released this year. Spring … Read the rest

JetBrains has made available the Kotlin/Native technology, which creates native binaries for Kotlin code so they can run without a Java virtual machine. A beta version of the CLion IDE allows Kotlin programs to be compiled directly to an executable machine-code format.

Kotlin is a statically typed Java language alternative that began on the JVM. But many platforms can’t run JVMs, restricting the use of Kotlin to JVM-friendly platforms like Android. The Kotlin/Native preview’s supported target platforms include MacOS, iOS, … Read the rest

When it comes to which languages developers like and dislike, Stack Overflow has some insight. Based on the languages developers tagged as those they would not like to work with in their Stack Overflow Jobs profiles, the company has found that Perl, Delphi, Visual Basic for Applications (VBA), and PHP are the most disliked programming languages, while R, Kotlin, TypeScript, and Rust are the least disliked.

Version 1.2 of the statically typed Kotlin language, will offer an experimental feature enabling reuse of code across platforms, as well as compatibility with the Java 9 module system. The beta of Kotlin 1.2 is now available for download.

Kotlin’s experimental multiplatform projects capability lets developers reuse code between supported target platforms: JVM and JavaScript initially, and later native. Code to be shared between platforms is placed in a common module; platform-dependent parts are put in platform-specific modules. … Read the rest
