JavaScript疲れを脱する - React編 というブログエントリを読んでみた - ryhmrt’s blog
最近 React + Redux でSPAをやっていて、パフォーマンスとかいろいろ問題が出てきています。 試行錯誤を繰り返す中、チームメンバーが "Getting Out of JavaScript Fatigue - React Edition" というブログ記事を紹介してくれました。 Reading Hacker News comments on JavaScript frontend articles is a depressing task these days. The majority is complaining: Tooling too complex, bundling too complex, Too many different frameworks, best practices change too quickly. 出だしから「最近 Hacker News でフ
Cerebral Docs
It makes perfect sense for us to write our UIs with declarative code. The reason is that we need to reuse UI elements and compose them together in different configurations. UIs are complex. IMPERATIVE const list = document.createElement('ul') const item1 = document.createElement('li') const item2 = document.createElement('li') item1.innerHTML = 'Item 1' item2.innerHTML = 'Item 2' list.appendChild(

Elmish: Functional Programming in Javascript
For the past few months, I’ve been on adventure learning everything I could about functional programming. It seems like every week there’s a new frontend framework or library claiming some inspiration from functional programming, so I decided to check it out. One of my explorations was into Elm: an amazing Haskell-inspired language for building web applications. It gave me a taste of what function
async/await: It’s Good and Bad
This might be controversial, as most people I know are huge fans of async/await. If you’re not familiar, it’s this nifty little syntax addition that allows developers to deal with APIs that return Promises in a more “native” way: async function doSomethingCool() { let someValue = await getSomePromise(); console.log(someValue + '!!!'); }As opposed to: function doSomethingCool() { getSomePromise.the
react-hyperscript-helpers
react-hyperscript-helpers2.0.0 • Public • Published 6 years ago react-hyperscript-helpers A library inspired by hyperscript-helpers and react-hyperscript. Allows for expressing UIs in the hyperscript-helpers style but with first class support for React. Why?

Understand promises before you start using async/await
With Babel now supporting async/await out of the box, and ES2016 (or ES7) just around the corner, more and more people are realizing how awesome this pattern is for writing asynchronous code, using synchronous code structure. This is a good thing™, and ought to improve code quality a whole lot. However, what a lot of people may have missed is that the entire foundation for async/await is promises.
