It’s Friday again: Time for the second issue of This Week In React ⚛️.

💌 Starting this week, there’s also an email newsletter. If you prefer that format, subscribe at this-week-in-react.org and tell your friends!

Now let’s go! Thread ➡️
🔥 Andrew (@acdlite) added pure(), a new HOC to bring PureComponent behavior to functional components. 🔥

const MyPureComponent = pure(MyComponent);

This is incredibly exciting and will be useful in so many situations. 🤯

📚 Brian (@brian_d_vaughn) added an API that adds this.context in all callbacks of class components and simplifies migration to the new context:

class extends Component {
static contextType = MyContext;
render() {
return this.context;
}
}

github.com/facebook/react…
👀 After previous tweets by the React Core team (e.g. ), Dominic (@trueadm) now landed a commit that renames AsyncMode to ConcurrentMode.

Async React is now Concurrent React!

github.com/facebook/react…
⚡️ Alex Reardon (@alexandereardon) started an interesting discussion about comparing the performance of react-redux to a single, shared React Context. Dig in for insights into the different models and their restrictions.

github.com/facebook/react…
⏳ Andrew (@acdlite) also added an API for modifying priority levels to the scheduler. This makes it possible to enqueue high priority state changes that should be flushed earlier.

Expect an RFC soon to finalize the names.

🎟 Sergei Startsev (sergei-startsev) worked on a fix to prevent React from overwriting window.event in event callbacks when using a development build. The PR is also a great example of the throughout manual testing we do for React DOM.

github.com/facebook/react…
🔭 React is currently listening to DOM events on the document level. If you’re curious about potential alternatives which we’re considering as part of React Fire, check out my write-up about this topic.

🙌 Special thanks to our first-time contributors this week: Brian Ng (@existentialism), Dustin Schau (@SchauDustin), Lionel (elrumordelaluz), and Sergei Startsev (sergei-startsev).

And that was all for This Week In React ⚛️

Another week has passed and it’s time for another This Week In React ⚛️.

Enable getDerivedStateFromError, Create React App 2.0, A Jest Helper for Concurrent Tests, and a lot more.

Subscribe at this-week-in-react.org or read the thread ➡️
💥 getDerivedStateFromError is a new lifecycle method that is invoked after an error has been thrown by a descendant component. With that, you directly update a component’s state based on the error. Learn more in the open docs PR.

github.com/facebook/react…
🎉 This week, Create React App 2.0 was released bringing a year’s worth of improvements with it. Most notably support for SASS and Babel 7. Special thanks to @timer150 and everyone else involved.

1) I've been thinking about this all morning. Time for some speculation.

It's regarding Tucker Carlson. I think the "secret hand" wants him gone. #QAnon
2) First, some lead up into why I sense this is going on.

There were 2 triggers. First was the recent George Papadopoulos interview. It was an important interview, it dealt with Mifsud. I think it was squashed by the network. #QAnon

Here it is:

3) Notice Tucker says "I wish we have an hour to talk, but we have about 45 seconds" -Tucker was not happy. I don't recall him being on again since. #QAnon

“Smell am!” He screamed, pressing the cold metal on my nose.

“Wetin be dis?”

“Na gun” I said, as boiling point urine dropped on my boxers.

Guns are sexy in movies when with it, the actor kills 95 bad guys. Not as much in real life, pointed at you.

Brethren, I live my life I no like trouble.

Yet somehow, even in the most innocuous situations, these village Chinwetalu Agu et al manage to sneak wahala into everything.

I had enjoyed four blissful months with Pamela. A very adventurous young lady, fun and crazy to be with.
We met at the birthday Dinner of someone hanging somewhere on Progress’s family tree.

He said the celebrant was his Aunty’s brother’s friend’s cousin....

I zoned out after cousin like “Baba abi food go dey? Let’s go. Happy birthday to your grandSister.

Wetin concern me?”

.@ChuckGrassley @realDonaldTrump @POTUS

IMO: we need MUCH TOUGHER laws on illegal-drug financing, manufacturing & whole-sale level distribution along with RICO enforcement. Retail level distribution & use consequences MUST BE DEFINITIVE and EQUITABLE in application across US.
.@ChuckGrassley @realDonaldTrump @POTUS

DEFINITIVE and EQUITABLE means that you can not throw the poor, the black, & other minorities in JAIL and the rich-white-kid gets help thanks to lawyers & parents.

Statistics suggest Lady Justice is NOT blind; that's a problem.
.@ChuckGrassley @realDonaldTrump @POTUS

Illegal-Drugs are harmful & deadly (like alcohol & cigarettes); some limited medical or recreational use.

Re-classify drugs as: NO-Medical-Approval-Drugs (NOMAD) for ATF sale (COMPETE, TAX, REGISTER, TRACK, EDUCATE, CONTROL & REDUCE USE).

Are you one of those people who's looked back on 2017 and convinced yourself that you haven't achieved anything? Worried about catching up with your mates who seem to have done much better?

Let me tell you a story about #time.

A thread 👇
A long #time ago, back when I was about twelve or thirteen years old, my parents travelled to Uyo.

Before leaving, my mother asked me to prepare Edikang ikong soup so she and my father would eat when they returned.
When I was finished with the soup, it was supposed to look something like this:
