**Yarn 4.0 is Here: What's New for You!**

Hello Guys, My Name is [Md Taqui Imam](https://bit.ly/MdTaqui), Today, we've got some **exciting news for you**. **Yarn 4.0 has just hit the scene**, and it's bringing some cool new stuff with it. So, let's break it down in a way that's super easy to understand.

{% cta https://github.com/taqui-786 %}Follow me in Github{% endcta %}

> Let's Begin 👇

**1. Node.js 18+:**
If you're already using Yarn or thinking about giving it a try, you need to know that it now requires Node.js version 18 or higher. This means your projects will need to run on the latest Node.js.

**2. Zero-Install Changes:**
When you create new projects with `yarn init`, they won't use Zero-Install by default anymore. Also, Yarn now uses something called Corepack, which is a tool that helps manage different package manager versions for your projects. It's all about making things simpler for you.

**3. All Official Plugins Included:**
The official plugins like TypeScript and interactive tools are now included by default. You won't have to worry about adding them separately.

**4. Hardened Mode:**
Yarn now has a Hardened Mode to protect your projects from sneaky attacks. This mode checks that the package information in your project matches with the remote registry. It's like having an extra layer of security for your projects.

**5. JavaScript Constraints:**
Yarn 4.0 introduces a new JavaScript-based engine for constraints. It's a fancy way of making sure your project follows certain rules. You can use these rules to keep your project organized and error-free.

**6. TypeScript Integration and More:**
Now, you can use TypeScript more easily, and you won't need to worry about managing plugins separately. Everything you need is included in the main distribution.

**7. Improved User Interface:**
The user interface has gotten a makeover. You'll get more helpful information, and there won't be as many confusing warnings. It's all about making your experience smoother.

**8. Performance Boost:**
Yarn 4.0 is faster than ever before. It can install your packages much quicker, thanks to a new package metadata cache. Your projects will run like lightning!

**9. Fancy Website:**
If you've visited Yarn's website, you'll notice it's had a facelift. Now it's easier to find what you need, with links to documentation and tooltips explaining options.

**10. The Future of Yarn:**
The Yarn team is always thinking about what's next. They might even look into making Yarn even faster in the future. But don't worry, they won't make big changes that make things harder for you.

So, there you have it, Yarn 4.0 in a nutshell. It's all about making your coding projects easier and more secure. Whether you're just starting or already a pro, Yarn 4.0 is here to help you on your coding adventures. Have fun exploring all the new features, and happy coding! 🚀✨

The Complete Guide to Time Series Models
Published: 2023-10-24 14:14:50

Define the problem: Clearly define the problem you want to solve with your time-series model. Determine the specific task, such as forecasting future values, detecting anomalies, or identifying patterns.

Gather and preprocess the data: Collect the relevant time-series data for your problem. Ensure that the data is in a suitable format, such as a CSV file or a database. Preprocess the data by handling missing values, outliers, and any necessary transformations (e.g., scaling or differencing).

Split the data: Divide your dataset into training, validation, and test sets. The training set is used to train the model, the validation set is used for hyperparameter tuning and model selection, and the test set is kept separate for final evaluation.

Explore the data: Perform an exploratory data analysis (EDA) to gain insights into the data. Visualize the time series, check for trends, seasonality, and correlations. This step helps you understand the characteristics of your data and identify any patterns that may exist.

Choose a model: Select an appropriate time-series model based on the characteristics of your data and the problem you are trying to solve. Common models include autoregressive integrated moving average (ARIMA), seasonal ARIMA (SARIMA), exponential smoothing (ETS), or more advanced models like Long Short-Term Memory (LSTM) networks.

Train the model: Train your chosen model using the training data. The training process involves optimizing the model's parameters to minimize the difference between the predicted values and the actual values in the training set. The specific training method depends on the chosen model.

Validate and tune the model: Evaluate the performance of your model using the validation set. Measure the accuracy or error metrics relevant to your problem (e.g., mean squared error, mean absolute error). Adjust the model's hyperparameters, such as the order of the ARIMA model or the number of LSTM layers, using techniques like grid search or random search.

Evaluate the model: Once you have selected the best-performing model based on the validation set, evaluate its performance on the test set. Compare the predicted values with the actual values in the test set to assess how well the model generalizes to unseen data.

Refine and iterate: Iterate on the previous steps to improve your model. You may need to revisit the data preprocessing, feature engineering, or model selection to achieve better results. Experiment with different models, hyperparameters, or even try ensemble techniques.

Deploy and monitor: Once you are satisfied with the model's performance, deploy it in a production environment if applicable. Monitor its performance regularly and retrain or update the model as new data becomes available or the problem requirements change.

Deployment Patterns in Kubernetes
Published: 2023-10-24 14:08:05

# Deployment Patterns

In this post, I will discuss different deployment patterns that you can use to deploy your application. I will also discuss how you can implement these deployment patterns in Kubernetes.

## Recreate

With this deployment pattern, you deploy a new version of your application and delete the existing version of the application. This is the simplest deployment pattern, but it can result in downtime for your application as shown in the following diagram.

![Recreate](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uzdpx065plui5nkmich9.png))


## Ramped

With this deployment pattern, you deploy a new version of your application alongside the existing version of the application. Once the new version is ready, you gradually shift traffic from the existing version to the new version. This is the default deployment strategy in Kubernetes.

![Ramped](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hgl46xy1d50sy9mj9zwr.png)

## Canary

With this deployment pattern, you deploy a new version of your application alongside the existing version of the application. Once the new version is ready, you shift a small percentage of traffic from the existing version to the new version. If the new version performs well, you continue shifting traffic until all traffic is shifted to the new version. If the new version performs poorly, you stop shifting traffic and continue to use the existing version.

## Blue/Green

With this deployment pattern, you deploy a new version of your application alongside the existing version of the application. Once the new version is ready, you switch traffic from the existing version to the new version.

![Blue Green](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vnkzsyk6cetef7a3l54l.png)

## A/B Testing

With this deployment pattern, you can test a new version of your application by deploying it to a subset of users alongside the existing version of the application.

![A/B Testing](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/difxn1yolp2bu46n3xuu.png)

## Shadow

With this deployment pattern, you can test a new version of your application by deploying it alongside the existing version of the application. However, instead of sending client traffic to the new version, you send a copy of the traffic to the new version. This allows you to test the new version without impacting the existing version.

Hopefully, this post has given you a better understanding of different deployment patterns that you can use to deploy your application.

JS devs, what's your take on marketing content?
Tags: javascript, healthydebate, discuss
Published: 2023-10-24 13:11:37

I work behind the scenes in web development, and I’m trying to figure out: How marketing influences your decisions when picking new platforms or tools.

I've noticed a trend where bold claims often lack substantial backing, which isn't just frustrating, it's counterproductive. Like the marketer who cried wolf. So... I'm gathering insights for a project aimed at conceptualising a more transparent approach in how we as marketers speak about dev tools.

My question is: If you could change how these tools are marketed, what would you prioritise? What kind of promises or cliches make you skeptical, or even outright dismissive?

Your insights are purely for my understanding but my hope is that they will inspire a new, wholly beneficial approach and cause a domino effect across the industry. No hidden agenda, I'm just genuinely passionate about what I do and how that can bring the most value to my audience.

Huge thanks for taking the time to read this and (hopefully) respond. Your perspective is invaluable, and I'm exceptionally grateful for any contributions.

useEffect Hook💥 in React
Tags: react, useeffect, hooks, tutorial
Published: 2023-10-24 13:01:49

React Hooks are a feature introduced in version 16.8 of React. They allow function components to have access to state and other React features, such as lifecycle methods, without the need for class components.

Today we are seeing about useEffect hook in react.

The useEffect Hook allows you to perform side effects in your components.
Some examples of side effects are: fetching data, directly updating the DOM, and timers.
useEffect accepts two arguments. The second argument is optional.

`useEffect(<function>, <dependency>)`

`<function>` — inside the function we write a callBack function.

`<dependency>` — inside the dependency we should give a dependency array.

the below example have contents in app.js

```
import './App.css';
import { useState, useEffect } from 'react';

function App() {
  const [count, setCount] = useState(0);
 
  useEffect(()=>{
    // this hook will run at the time when our component mounts.

    console.log('the count is',count);

    // this is optional return statement, is that what will happen when
    // the component unmounts.

    return () =>{
        console.log('the component was unmounted')
    }

    // what we are using inside of useEffect we must metion that 
    // inside of dependency array. 
    // the code inside the useeffect will execute once, aftee that it 
    // won't execuded when we forget to give values inside the dependency array

  }, [count]);

  return (
    <div className='App'>
      <p>Count: {count}</p>
      <button onClick={() => setCount((c) => c + 1)}>+</button>
    </div>
  );
}

export default App;
```
Here we should know that how useEffect works, it will execute the code at the component mounts after that at every time we update the values inside the dependency array the component will destroy and rebuild again,
that is the return function inside the useEffect hook will execute at the time.

The output for this above code will be,

![output image](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qb7i0zreg6r0qiys2luo.png)

you will see the changes in the console by inspecting that webpage

the console will be,

![output in console](https://miro.medium.com/v2/resize:fit:720/format:webp/1*BY4DH1Ifsnp4maqmsxKBsA.png)

At every time the count value changes the component will destroy and again it would mount in the component tree.

I hope that you will have a better understanding of useEffect, If you have any doubts comment in this post.

Thank you, Have a nice day 💖…….
