The most important thing about React's update performance is that it's ~O(n) of the size of the virtual dom. If React's performance is a problem you can window the input data, do things more efficiently in your render, tweak

Current stack at work for me is Clojurescript / Reagent / Boot. In JS land, I'm in the React camp. React's model is the biggest step forward on the frontend since jQuery. I stick with React over faster/smaller alter

Ember is IMO second best at everything, which is pretty good for a fully integrated stack. If you don't have a very good idea of what you want to use for all the pieces of your app, you're working with a group of less experienced

CEF is the API used to embed Webkit (now Blink). Servo is Mozilla's new research rendering engine, it's adopting the CEF API to make embedding easier for people.

Doing everything in parallel is pretty much the point of the project. I'm not directly involved but I have been watching the project. There a few specific parts of layout that can't be parallelized[0] but pretty much every page [1

You're in luck. ES6 introduces quasi-literals which are multi-line and will do exactly what you want. You can even tag them to set up parsing. jsx`<div><p>${hello_world}</p></div>` I don'

Are you counting Java IDE keystrokes or actual number of characters on the screen? If it's the latter, I'd be interested in seeing an example since it's very much against the wisdom of the crowds here. My experience is that t

> Why not just make smaller apps, or make smaller things that compose with less knowledge of where they are? The easy answer to this is that successful apps have a tendency to grow larger than expected and splitting them up requires care

It is difficult, which is why Clojurescript adoption didn't really take off until React (via Om) showed up. The whole point of the virtual dom model is to avoid stateful DOM manipulation and instead have view code that is an idempotent

There's no overhead in caling a C api nor in other code calling Rust code as if it were a C api. There's FFI setup and some caveats both ways but a lot of the larger Rust projects involve (e.g Servo, Piston) interfacing with pre-e

It's primarily a bundle maker a la browserify. The main difference is that it stretches the definition of module beyond just javascript. It can seem like a build system because you can set up rules to run a particular filter on a match

You need to know Javascript's quirks. I generally recommend [1] for experienced developers. Everything on that page is important to know (edit: except the perf stuff, which changes as the js engines get better). I'll second the El

The vast majority of things in webdev land work similarly to something else. The trick is to learn the underlying pattern and then just remember the parts that make a specific implementation of the idea different. The exception tends to be

Flux, as prescribed by Facebook, involves a couple singletons and implementing an action requires coordinated changes across 3-4 files. Many people find this undesirable. The important part about the pattern is the unidirectional data flow,
