Mastering Date Sorting in React: A Guide to Handling Time Differences and Displaying Chronological Data
Tags: javascript, react, date
Published: 2023-12-19 10:20:54

`const [sortedDates, setSortedDates] = useState([]);

useEffect(() => {
  const dateStrings = row.map((m) => m.meettimeUTC);

  const currentDate = new Date();

  const sortedObjects = dateObjects.sort((a, b) => {
    const timeDiffA = a - currentDate;
    const timeDiffB = b - currentDate;

  setSortedDates(sortedDateStrings);
}, [row]);`
Some Best Practices For Handling Errors In JavaScript:
Published: 2023-12-19 10:05:08

1. Use try...catch blocks: This is the most common way to handle synchronous errors. It allows you to "try" a block of code and "catch" any errors that occur.

```
try {
    // Code that may throw an error
} catch (error) {
    // Handle the error
}
```

2. Throw your own errors: If you detect a condition that could cause problems later, you can throw your own error with the throw statement.

```
if (someCondition) {
    throw new Error('This is a custom error message');
}

```

3. Use Promise.catch() for asynchronous errors: Promises are a common way to handle asynchronous operations in JavaScript. If an error occurs in a promise, it can be caught with .catch().

```
someAsyncFunction()
    .then(result => {
        // Handle the result
    })
    .catch(error => {
        // Handle the error
    });

```
4. Always deal with errors: Never leave a catch block empty. Even if you think an error can't or won't occur, it's still good practice to handle it.

5. Use error-first callbacks: In Node.js, it's common to use callbacks to handle asynchronous operations. The convention is to make the first parameter of the callback an error object. If there is no error, the first parameter will be null.

```
fs.readFile('somefile.txt', (err, data) => {
    if (err) {
        // Handle the error
    } else {
        // Handle the data
    }
});

```

6. Use a logging service: It's important to keep track of errors that occur in your application. A logging service can help you do this.

7. Don't suppress errors: Unless you have a very good reason, don't suppress errors by simply logging them and not re-throwing them or passing them along. This can make debugging very difficult.

8. Use finally blocks: finally blocks can be used to clean up after your code, whether an error occurred or not.

```
try {
    // Code that may throw an error
} catch (error) {
    // Handle the error
} finally {
    // Cleanup code
}
```
9. Understand the different types of Error objects: JavaScript has several built-in error constructors, such as Error(), RangeError(), TypeError(), and more. These can be used to throw more specific types of errors.

Top 5 crypto events in 2023:
Tags: cryptocurrency, news, 2023, exchange
Published: 2023-12-19 09:59:26

Soon it will be Christmas, followed by the New Year so it's time to take stock of this year's results
The year 2023 was very saturated with crypto news, but I wanted to highlight the top 5 brightest ones 

1. [**TOKEN2049**](https://cointelegraph.com/press-releases/token2049-singapore-set-to-be-worlds-largest-web3-event-with-over-10-000-attendees)
TOKEN2049 is the premier Web3 event organized annually in Singapore
This event has become the most global event in the history of the crypto world this year 

2. [**Falling NFT market**](https://www.coindesk.com/consensus-magazine/2023/10/31/the-nft-market-has-crashed-what-should-artists-do-now/)
The fall of the NFT market has become a real phenomenon in 2023 
I wonder what will happen to NFT in 2024? Your bets. 

3. [**A colossal upheaval at Binance**](https://www.bloomberg.com/news/articles/2023-11-21/binance-ceo-zhao-to-plead-guilty-in-us-settlement-wsj?embedded-checkout=true)
This year the Binance exchange shocked users with sharp news that led to mixed reviews from users. 
Well, we're sitting on the fence, watching. 

4. [**Crypto Scaling the European Market**](https://bithub.pl/kryptowaluty/gielda-whitebit-wkracza-do-polski-zapytalismy-co-wyjatkowego-chca-zaproponowac-polskim-uzytkownikom-wywiad/)
The WhiteBIT exchange has finally entered the Polish market after successful launches on the Georgian and Spanish markets,  which, according to the feedback from users, have long been waiting for this exchange.   At the same time, Robinhood will onboard EU users under its Lithuania-licensed entity, and it has plans to offer additional services like crypto transfers and staking next year.

5. [**Bitcoin's volatility**](https://www.forbes.com/advisor/in/investing/cryptocurrency/bitcoin-prediction/)
Bitcoin has been as unpredictable this year as your ex.
But many analysts predict that by 2024 bitcoin may grow rapidly, so I envy those users who bought it at least 25 thousand dollars.

Cách gì làm tôi hiểu sâu hơn về Java/Java Spring Boot
Tags: vscode, learning, cleancode, springboot
Published: 2023-12-19 09:09:51

Vì tôi đang code bằng IDE VSCode, nên khi bắt đầu tiếp xúc và làm với Java Spring Boot, tôi đã cài 2 thứ khiến tôi dễ hiểu, tiếp cận nhanh hơn với Java cũng như code được clean hơn khi đi từ NodeJS qua.

## 1. Java format

Trong file settings.json, cài đặt như sau để IDE auto format code khi saved

```
"java.format.settings.url": "https://raw.githubusercontent.com/google/styleguide/gh-pages/eclipse-java-google-style.xml",
  "java.format.settings.profile": "GoogleStyle",
  "[java]": {
      "editor.formatOnSave": true,
      "editor.defaultFormatter": "redhat.java",
      "editor.tabSize": 2
  },
```

## 2. Java checker (important) - SonarLint

Install https://marketplace.visualstudio.com/items?itemName=SonarSource.sonarlint-vscode

SonarLint có các cảnh bảo về clean code, security, design pattern,... một cách chi tiết rõ ràng. Từ đó tôi hiểu được sâu và rõ hơn về Java Spring Boot

Ví dụ:

Laravel Events 101

description: Laravel Events
published: true
tags: laravel, events
//cover_image: https://vegibit.com/wp-content/uploads/2016/03/laravel-events-and-listeners.jpg
---

## What is Event-Driven Programming?

Simply put, events are actions that occur within an application. Coming from the world of JavaScript, you probably understand events as user actions such as mouse click, mouseover, key press, etc. In Laravel, events can be various actions that occur within an application such as email notifications, logging, user sign-up, CRUD operations, etc. Laravel events provide a simple observer implementation, allowing you to subscribe and listen for various events that occur in your application.

## Why should we use Events?!

- Easier to maintain (SOLID).
- Less risk of regression,
- Make classes responsible for only one thing,
- Make team’s work easier,
- Expect the unexpected, If you ever need to add new functionality, all you need to do is create a new listener and register it with the event. Job is done!
- Your logic is separated and now the Controller has much-reduced responsibility
- Allow asynchronous tasks easily (queues in Laravel).
- Be ready for broadcasting

## Let's compare two pieces of code with/without events

### With

### Without
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/qdpjjp8cdroftvyn4yed.png)

## How do we create Events?

### Defining Our Events

```php artisan make:event UserRegistered```

The event has been created successfully

```php artisan make:listener SendWelcomeMail --event=UserRegistered```

The listener has been created successfully

```php artisan make:listener SignupForWeeklyNewsletter --event=UserRegistered```

The listener has been created successfully

```php artisan make:listener SendSMS --event=UserRegistered```

The listener has been created successfully

## ESP - EventServiceProvider

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/0svwe6ivibsptoew00nw.png)

```php artisan event:generate```

Events and Listeners generated successfully

## Stopping The Propagation Of An Event

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/i1pjxkfyjxmvy95ct6f2.png)

## Eloquent Native Events

With his Eloquent model, Laravel will automatically fire **created**, **saved**, **updated** and **deleted** events respectively.

To start listening to model events, define a **$dispatchesEvents** property on your Eloquent model. This property maps various points of the Eloquent **model's** lifecycle to your event classes. Each model event class should expect to receive an instance of the affected model via its constructor.
