The best articles, links and news related to Frontend Development, and more, delivered once a week. All reference in this issue are gathered from Medium, Hacker News, Reddit,Twitter, MyBridge, etc.

More Issues can be found in Frontend+ Weekly Repository.


  • WebAssembly architecture for Go: This documents describes the design decisions that went into the new WebAssembly architecture (short “wasm”) for the Go compiler. The goal is to upstream it to the official Go repository in the current development cycle, targeting Go 1.11. The WebAssembly architecture will allow Go to become an alternative to JavaScript for writing code that runs in a web browser. This new freedom of choice will hopefully have a positive impact on the software engineering ecosystem overall.

  • Announcing Flutter beta 1: Build beautiful native apps: as part of Mobile World Congress 2018, the first beta release of Flutter is announced. Flutter is Google's new mobile UI framework that helps developers craft high-quality native interfaces for both iOS and Android. Flutter targets the sweet spot of mobile development: performance and platform integrations of native mobile, with high-velocity development and multi-platform reach of portable UI toolkits.

  • PhantomJS: Archiving the project, suspending development: Due to the lack of active contribution, PhantomJS will be archived soon and stop the development. PhantomJS version 2.1.1 will remain the last known stable release until further notice. Chrome and Firefox gaining headless modes is the ultimate goal Phantom could've achieved, but it served its purpose very well, while it was needed. Thanks & Goodbye.


  • Google releases machine learning course: As part of Google’s transition into an AI first world, the company wants to widely open up this technology. Its latest initiative involves a new website with a number of resources, as well as a previously internal online learning course. “Learn with Google AI” is a new educational addition to a site originally announced at the I/O developer conference last year. In recent years, the company has repeatedly stated that its goal is to democratize AI and make its tool available for everyone. More changelogs can be found in this.

Under the hood

  • Didact Fiber: Incremental reconciliation: This is a really nice deep dive into a sketch of Fiber implementation.

Why or why not? ould we make a better state management solution? If so, how? More changelogs can be found in this.

  • Tracing from JS to the DOM and back again: Debugging memory leaks in Chrome 66 just became much easier. Chrome’s DevTools can now trace and snapshot C++ DOM objects and display all reachable DOM objects from JavaScript with their references. This feature is one of the benefits of the new C++ tracing mechanism of the V8 garbage collector. More changelogs can be found in this.
