Babel 7 released

After almost 2 years, 4k commits, over 50 pre-releases, and a lot of help we are excited to announce the release of Babel 7. It's been almost 3 years since the release of Babel 6! There's a lot of moving parts so please bear with us in the first weeks of release. Babel's role in the JavaScript ecosystem... Babel is fundamental to JavaScript development today. There are currently over 1.3 million dependent repos on GitHub, 17 million downloads on npm per month, and hundreds of users including many major frameworks (React, Vue, Ember, Polymer), and companies (Facebook, Netflix, Airbnb). It has become such a foundation for JavaScript development that many people don't even know that it is being used. Even if you aren't using it yourself, it's highly likely your dependencies are using Babel.

Vue CLI 3.0 is here!

Good news — the next generation of Vue CLI, the standard build toolchain for Vue applications, is here. Evan You writes: Vue CLI 3 is a completely different beast from its previous version. The goal of the rewrite is two-fold: Reduce configuration fatigue of modern frontend tooling, especially when mixing multiple tools together; Incorporate best practices in the toolchain as much as possible so it becomes the default for any Vue app. This means that any Vue CLI 3 project comes with out-of-the-box support most of today's preferred ways to build and ship applications.

How far can JavaScript take us?

Tanner Villarete asked himself, "How far can JavaScript take us?" Then answered: Turns out, pretty dang far. This web app was my attempt at mimicking Apple's iOS music app, and I think I've come pretty close! I have to admit, he did a pretty good job. The frontend is built on React and Redux. The backend? A Laravel-based API running on a Raspberry Pi! Here's the live demo, but be nice because Raspberry Pi.

Is WebAssembly the return of Java Applets & Flash?

A lot of people wanted Steve Klabnik to elaborate on this from a recent post on WebAssembly... Some have compared WebAssembly to Java applets; in some ways, they’re very right, but in some ways, they’re very wrong. Eventually I’ll write a post about the wrong, but for now, the right: in some sense, WebAssembly is a different way of accomplishing what the JVM set out to do: it’s a common virtual machine that can be used to build very cross-platform software. Here's a great take away if all you want is a tldr... Java Applets and Flash were security nightmares. WebAssembly, on the other hand, piggybacks on the JavaScript VM. All of the effort going into creating its sandbox also applies to Wasm.

Making calls to WebAssembly blazingly fast

Benjamin Bouvier, Compiler Engineer at Mozilla, writes about speeding up calls from JS to Wasm in Firefox. If we want more WebAssembly (wasm) adoption, there shouldn't be a big costly barrier between the two universes. That is, calls from one world to the other should be fast. For a very long time, calls from JS to asm.js/WebAssembly have been quite slow in Firefox. In fact, we didn't optimize them at all. He goes on to say... Starting with Firefox 60, the JIT compiler makes no distinctions between calling a JavaScript function or a WebAssembly function, meaning it uses the same call optimizations for both kinds of function. Benjamin continues through several more bugs mentioned on the Bugzilla bug board with fixes to speed up calls from JS to Wasm in Firefox.
