**JavaScript** is a super cool language with lots of neat stuff, but guess what? JavaScript has some cool secret tricks that can make coding even more fun. Let me show you these hidden gems and how they can make your code better and your projects awesome!


- **Object.freeze()**

The Object.freeze() method allows you to freeze an object, preventing any changes to its properties or prototype. This can be useful to ensure that an object remains immutable and its properties cannot be modified accidentally.

```javascript
const person = {
  name: 'John',
  age: 30
};


Object.freeze(person);

person.age = 40; // This will not have any effect
console.log(person); // Output: { name: 'John', age: 30 }

```


- **String.padStart() and String.padEnd()**

The String.padStart() and String.padEnd() methods pad the current string with another string (repeated, if needed) so that the resulting string reaches the given length. These methods are useful for formatting strings, especially for aligning text in tables or UI elements.


```javascript
const number = '123';
console.log(number.padStart(5, '0')); // Output: 00123

const message = 'Hello';
console.log(message.padEnd(10, '!')); // Output: Hello!!!!!
;
```

These methods provide a convenient way to format strings.


- **Array.prototype.flat()**

The Array.prototype.flat() method creates a new array with all sub-array elements concatenated into it recursively up to the specified depth. This can be handy for flattening arrays with nested arrays.

```javascript
const nestedArray = [1, [2, [3, [4]]]];
const flattenedArray = nestedArray.flat(Infinity);
console.log(flattenedArray); // Output: [1, 2, 3, 4]
```


- **String.prototype.trimStart() and String.prototype.trimEnd()**

These methods trim whitespace from the beginning (trimStart()) or end (trimEnd()) of a string. They are handy alternatives to String.prototype.trim() when you want to trim whitespace from specific sides of a string.

```javascript
const text = '   Hello, World!   ';

console.log(text.trimStart()); // Output: 'Hello, World!   '
console.log(text.trimEnd());   // Output: '   Hello, World!'
```


- **Object.fromEntries()**

The Object.fromEntries() method transforms a list of key-value pairs into an object. It is the counterpart of Object.entries(), which returns an array of key-value pairs from an object.

```javascript
const entries = [['name', 'John'], ['age', 30]];
const person = Object.fromEntries(entries);
console.log(person); // Output: { name: 'John', age: 30 }
```


**Conclusion**
JavaScript has some really cool secrets that can make your code shorter, easier to understand and work better. Knowing and using these special features can make you a better JavaScript coder and make your projects look awesome.

So, next time you're coding in JavaScript, remember to explore these hidden treasures!

I hope you found these JavaScript tricks helpful! Feel free to share any more cool JavaScript tips you know in the comments below.

টাইপস্ক্রিপ্ট মুলত একটি Javascript ভিত্তিক প্রোগ্রামিং ভাষা। যা ডেবলপারদের কোডে ডাটা টাইপিং মিস্টেক এর হাত থেকে রক্ষা করে। যেমন: জাভাস্ক্রিপ্ট এ আমরা যদি কোনো অবজেক্ট ডিক্লেয়ার করি তখন সেখানে কিন্তু আমরা কোনো টাইপ বলে দি না। তখন কিন্তু আমাদের কোডে এক প্রকার একটা ডাটা টাইপিং এ প্রবলেম হতে পারে, যেমন আমরা ইনপুট হিসেবে চাইলাম ইউজার এর নাম ; অবশ্যই সেটা স্ট্রি হতে হবে, আমরাও জানি সেটা স্ট্রিং হবে, প্রবলেম টা হবে তখনই যখন ইনপুট হিসেবে আমরা স্ট্রিং এর বদলে অন্য কোন টাইপ দিবো। তখন কিন্তু একটা প্রবলেম মাস্ট হবে।
তো এই প্রবলেমটাকে হ্যান্ডেল করার জন্য মুলত টাইপ স্ক্রিপ্ট মামাকে তৈরি করা হয়েছে।

এই টাইস্ক্রিপ্ট আমাদের কোড করার সময়ই দিক নির্দেশনা দিয়ে দিবে যেমনটা আমরা তাকে আগে বলে দিসি।
যেমন: একটা অবজেক্ট ডিক্লেয়ার করার সময় বলে দিতে হয় যে, এই প্রোপার্টির এই এই টাইপ হবে, তখন যদি আমরা ভুলে বা বে খেয়ালে টাইপ ভুল করি তখনই আমাদের টাইপস্ক্রিপ্ট বলে দিবে যে ভাই আমাকে তুমরা এই এই টাইপ দিবে বলসো কিন্তু এখন অন্য একটা দিচ্ছো,এইটা কিন্তু সেই মাইন্ড করবে।


সো আমার দিক থেকে টাইপ স্ক্রিপ্ট এর এই ব্যাপারটা খুব মজা লাগছে বিষয়টা ভালো লাগছে।
ReactJs Bangla

এক দিনে প্রায় দু'শ মিলিয়ন ডেভেলপার ReactJS ব্যবহার করে অ্যাপ্লিকেশন তৈরি করছেন। এটি একটি জনপ্রিয় JavaScript লাইব্রেরি, যা ওয়েব অ্যাপ্লিকেশন বিকাশে একটি দ্রুত, কার্যকর, এবং বহুল প্রয়োগ পাওয়া টুলসেট প্রদান করে। আসুন দেখে নেই কেন ReactJS এতটাই জনপ্রিয় এবং কেন এটি ডেভেলপারদের পছন্দের তালিকায় অধিকতরে রয়েছে।

ReactJs কি?
ReactJS হ'ল একটি ওয়েব ডেভেলপমেন্ট লাইব্রেরি যা ফেসবুক দ্বারা তৈরি করা হয়েছে। এটি একটি ওয়েব অ্যাপ্লিকেশন তৈরির জন্য ব্যবহৃত হয়, যা দ্রুত, প্রতিক্রিয়াশী এবং একটি স্কেলাবল ইউজার ইন্টারফেস তৈরি করতে সাহায্য করে। React এর বৈশিষ্ট্যগুলির মধ্যে প্রধান হল কম্পোনেন্ট ভিত্তিক ডেভেলপমেন্ট, একল স্টেট ম্যানেজমেন্ট, এবং ভার্চুয়াল ডোম।

কেন ReactJS ?
1: কম্পোনেন্ট ভিত্তিক ডেভেলপমেন্ট: ReactJS-এ এপ্লিকেশন ডেভেলপমেন্ট হলো কম্পোনেন্ট ভিত্তিক। প্রতিটি বিষয়বস্তু একটি স্বতন্ত্র কম্পোনেন্ট হিসেবে প্রতিষ্ঠিত হয়, যা অন্যান্য কম্পোনেন্টগুলির সাথে সংযুক্ত হতে পারে। এটি ডেভেলপারদেরকে প্রোডাক্ট কোড এবং লোজিক পুনরাবৃত্তি করতে সাহায্য করে এবং কোড স্বল্পকালে রিও-ব্যবহারযোগ্য করে তোলে।

2: একল স্টেট ম্যানেজমেন্ট: ReactJS-এ, কম্পোনেন্টগুলির স্টেট একল হতে পারে, এবং এটি বেশ সহজেই আপডেট করা যায়। এটি একটি কম্পোনেন্টের স্টেট পরিবর্তন করলে কেবলমাত্র ওই কম্পোনেন্ট আপডেট হয়, যা কম সময়ে সাথে সাথে অ্যাপ্লিকেশনের কার্যকলাপ আপডেট করে তোলে।
3: ভার্চুয়াল ডোম: ReactJS একটি ভার্চুয়াল ডোম

Request for Authentication Every 1 Hour
Tags: nifi
Published: 2024-02-26 19:49:32

I have a NiFi server (version 1.15.3) with Google OpenID configured to authenticate users. This part of the authentication is working very well. However, every 1 hour after login, the user is logout and NiFi re-authenticates and returns to the NiFi home page.

I searched several forums on the internet for the variable responsible for controlling the logged-in user's session time. And none of the alternatives I found worked:

- _**nifi.security.user.saml.authentication.expiration=2**_ hours (apparently doesn't exist in the version I'm using)

_**nifi.security.user.jws.key.rotation.period=PT2H**_ (I changed from PT1H to PT2H but had no success either)

Does anyone have any other ideas?

Change the Remote URL of a Git Repository and Add a New One

Introduction:
Git is a powerful version control system widely used by developers to manage their code repositories. Occasionally, you may need to change the remote URL of your Git repository, perhaps due to a change in hosting provider or repository location. Additionally, you might want to add a new remote URL to your repository to collaborate with multiple remote repositories. In this article, we will guide you through the process of changing the remote URL of a Git repository and adding a new one.

Step 1: Check Current Remote URL(s)
Before making any changes, it's essential to know the current remote URL(s) associated with your Git repository. You can do this by running the following command in your terminal or command prompt:
```
git remote -v
```
This command will display the current remote URL(s) along with their corresponding names.

Step 2: Remove the Current Remote URL
To remove the current remote URL, you can use the following Git command:
```
git remote remove origin
```
Replace `origin` with the name of your current remote (typically named "origin").

Step 3: Add the New Remote URL
Now, you can add the new remote URL to your Git repository using the following command:
```
git remote add origin <new_remote_url>
```
Replace `<new_remote_url>` with the URL of your new repository.

Step 4: Verify the Changes
To ensure that the new remote URL has been added correctly, you can run the following command:
```
git remote -v
```
This command will display the updated list of remote URLs associated with your repository.

Step 5: Push Changes to the New Remote Repository
Finally, you can push your changes to the new remote repository using the following command:
```
git push -u origin main
```
Replace `main` with the name of the branch you want to push.

Conclusion:
Changing the remote URL of a Git repository and adding a new one is a straightforward process that can be done using a few Git commands. By following the steps outlined in this article, you can seamlessly transition your repository to a new remote location or collaborate with multiple remote repositories. Understanding how to manage remote URLs in Git is essential for efficient collaboration and version control in software development projects.

How to beat impostor syndrome in coding?
Tags: coding, programming, career, discuss
Published: 2024-02-26 18:29:51

I know that all coders face impostor syndrome at one point of time or another. Let us discuss on how to beat it. Leave your suggestions in the comments.

This is my suggestion: try learning a new tech stack, you will face difficulties and this will make you realize how good you are at the tech stack that you already know and use. That's it. Impostor Syndrome gone. Or at least reduced.
