⚛️ 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()

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

George Moller3 years ago

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!

Shripal Soni3 years ago

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

George Moller3 years ago

Glad you found it useful Shripal!

Vitalii, decaf developer3 years ago

Can you just remove from effect dependencies?

Csaba Kissi3 years ago

Great explanation George.

George Moller3 years ago

Thanks Csaba!

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."

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.

Just learnt in MGS4 you don't need to take down the beast form of the bosses non lethally, only when they shed said form do you need to use non lethal weapons. This is like my 10th playthru of this game I might be stupid.

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:

Here is: How illegal aliens are registered to vote: Gavin Newsom leads the way: At California DMVs, when you register to vote, you do not need to prove citizenship; you only need to check a box confirming, under an “honor system,” that you are legally eligible to vote. That’s why Democrats are obsessed with giving illegals voter IDs: driver’s licenses.

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.
