⚛️ Future React tip ↓ ❌ Omitting useEffect dependencies usually leads to hard-to-find bugs. ✅ Having said that, there are use cases when you need to run an effect only when reactive parts of the useEffect changes ↓ Extract non-reactive parts with useEffectEvent()

I've been working professionally with React for more than 8 years and I compiled all my knowledge into 100+ infographics just like this one. Check them out ↓

The amazing part about it, there is not single word about it in release notes. When did this land ? 🤔

It's not part of a stable React release yet, but you can find more info here I find this to be one missing piece for the useEffect hook, hope they release it soon!

I didn't know about `useEffectEvent` hook before. Nice tip, George 👍

Can you just remove from effect dependencies?

Is useEffectEvent already on React? The react documentation says "This section describes an experimental API that has not yet been released in a stable version of React."

Tamra Judge says she wasn’t mean to Shannon during the season instead she was “reactive.” Tamra says we don't see the things that are said/done to make her react the way she does… She says it's unfair to an extent that Bravo removes parts of arguments. #RHOC

Fighting games have an intimacy to them that other genres don't. But when your partners are a rotating roster of faceless nobodies in the FT2 online ranked grind, it's hard to feel the good parts of that intimacy. It's hard to feel anything other than anger.

React tip: "use client" misconceptions (1/5) 🚫 You need to mark EVERY individual file with "use client" to ensure it is a Client Component. ✅ You only need to mark each client entry point ONCE. Modules imported into a "use client" file are already part of the client bundle. (0:05) Adding "use client" to `3.js` marks the file as a client entry point, including it in the client bundle. (0:11) Importing `d()` into `3.js` (a client entry point) also includes it in the client bundle. (0:14) Adding "use client" to `4.js` has no additional bundling effect on `d()` because it is already part of the client bundle. (0:23) All modules (and their dependencies) imported to `3.js` are included in the client bundle. (0:26) Removing "use client" from `3.js` moves it and its dependencies into the server bundle.

Reactive Mainnet is Live! After a successful Testnet with well over 4M transactions, 200M origin events processed and dozens of innovative dApps and use cases devised, we've finally reached the day to launch the Reactive Network Mainnet! From day one Reactive Network will support as both origin and destination chains: 1️⃣ Ethereum Mainnet 2️⃣ Avalanche C-Chain 3️⃣ Base Chain 4️⃣ Binance Smart Chain 5️⃣ Polygon PoS With more on the way! REACT Token - However Mainnet wouldn't function without it's most core component the REACT token, which also goes into circulation today and serves multiple purposes within the Reactive Network ecosystem: Gas Fees: Pay for transactions on the network. Event Log Processing: Consumed as fees when executing Reactive Smart Contracts. Token Burn: Fees are burned, fueling the potential for a future deflationary model. Staking: Help to secure the network and earn rewards. Token Portal - Today we're also launching our Token Portal which will allow users to swap their $PRQ for $REACT and vice versa. As Reactive Network is based upon a Proof of Stake consensus mechanism staking will be available from day one, beginning with delegated staking which will also be done via our Token Portal here: Staking Terms - In response to our user feedback we've also adjusted our initial staking term from 6 months to 3 months. See our Staking Guide for full details on staking: More Questions? We've put together an FAQ to address the most common questions users may have:

Imagine hiding the deepest parts of yourself for your entire life. Never sharing them because you’re afraid of what people might think. Afraid you’re not enough. Afraid you’re too much. I think it’s a tragedy to keep those parts of yourself hidden, when deep down all you really want is to have them seen with love. One of my favourite things is when someone I love trusts me enough to share their whole heart. The messy parts. The broken parts. The most beautiful stories are never made up of only victorious chapters. “The wound is where the light enters you.”

“How hard should you kick a football” You cant quantify everything. A part of your performance will just be sheer instinct and intuition. This is usually gained through experience and repetitions. When to use an extra confirmation, when to just let a trade pass. When to get in early. When to leave a trade. There are a lot of intuitive decisions inside of trading. Nothing is totally mechanical. You have rules but you are still decision making.

This is when qabalis attacked Kashmir in 1947. My Nana would share similar stories of those time and tell us how ruthlessly these qabalis were, they killed a man just to steal his food. You will find many Kashmiris with unique surnames , they have added names of their native villages when they were forced to leave the northerners parts of Kashmir and move towards southern parts. These parts are now in Pakistan

When I said that automatic doors in Mumbai non-AC trains may not work, this is the demo. Frankly, Mumbai needs an RRTS system to run parallel to local trains and integrated with metro with an independent right of way.

So when you said on the radio, ‘the same thing again’, are you referring to your performance in qualifying?] Lewis: “Mhmm” *nods ‘yes’* [And you don’t know why?

You are faced with a terrible choice. Do you do what you know is right, even when it costs you? Do you speak when you’re afraid? Do you dare to show the parts of you that you once believed were unlovable? Disturb the dream. 🤍🖤

One of the reasons Dia is difficult to explain is because the most useful use cases are so specifically personal to you. When you find your moments with Dia, you can never go back to a traditional browser. This is how I use Dia to help myself outfit and engineer my ships in the game Elite Dangerous.

🚨 THEY'RE BURNING THE JUNKYARDS TO FORCE YOU TO GO ELECTRIC Sounds insane. Until you look at what's happening. An estimated 13 junkyards. Massive fires. Thousands of gas-powered vehicles reduced to ash. Gone overnight. Now ask yourself: What actually burns in a junkyard? - Engines - Transmissions - Alternators - Starters - Body panels The parts people need to keep older vehicles on the road. The parts that make gas-powered cars affordable. The parts that let people avoid buying something new. And while junkyards keep burning... the message never changes. Go electric. Go electric. Go electric. People believe the fires aren't destroying junk. They're destroying competition. You don't need to outlaw gas-powered vehicles. You don't need to confiscate them. You don't need to ban them. You only need to make them impossible to repair. Burn the parts. Raise the prices. Shrink the supply. Force the transition. One fire? An accident. Two fires? A coincidence. Thirteen? People start asking questions. No suspects. No admissions. No explanations that satisfy anyone. Yet the fires keep happening. The inventories keep disappearing. And the electric future keeps moving forward. The question isn't whether the fires are real. The question is: how many more junkyards have to burn before people start connecting the dots?
