JavaScript Promises: An Essential Guide
Tags: webdev, javascript, node, programming
Published: 2024-04-01 08:55:58

In the realm of JavaScript programming, managing asynchronous operations is a common challenge. Enter the JavaScript Promise - a powerful tool for handling asynchronous tasks in a more organized and manageable way.

{% youtube Wx2o-lnS8Bk %}


### What is a Promise?

At its core, a Promise represents the eventual completion or failure of an asynchronous operation and its resulting value. It serves as a placeholder for the result of an asynchronous task, allowing you to handle the outcome once it becomes available. Promises simplify asynchronous code by providing a clean and intuitive syntax for dealing with asynchronous operations.

### How Does it Work?

A Promise is created using the `new Promise()` constructor, which takes a function as an argument. This function, known as the "executor," receives two parameters: `resolve` and `reject`. Inside the executor function, you perform the asynchronous operation and then call `resolve` when it succeeds or `reject` when it encounters an error.

```javascript
const myPromise = new Promise((resolve, reject) => {
    // Perform asynchronous operation
    if (/* operation successful */) {
        resolve(/* result */);
    } else {
        reject(/* error */);
    }
});
```

Once the Promise is created, you can use the `.then()` method to handle the successful outcome and the `.catch()` method to handle any errors.

```javascript
myPromise.then((result) => {
    // Handle successful result
}).catch((error) => {
    // Handle error
});
```

### Conclusion:

[JavaScript Promises](https://qirolab.com/posts/what-is-javascript-promise-understanding-and-implementing-promises-in-js) provide a straightforward and elegant solution to the complexities of asynchronous programming. By encapsulating asynchronous operations in a Promise, you can write cleaner and more maintainable code. Whether you're fetching data from an API, performing file I/O, or executing any other asynchronous task, Promises offer a reliable and efficient way to manage asynchronous code flow.

In summary, [JavaScript Promises](https://www.youtube.com/watch?v=Wx2o-lnS8Bk) are a fundamental feature of modern JavaScript development, enabling developers to write more robust and scalable applications. Whether you're a seasoned JavaScript developer or just starting out, mastering Promises is essential for building high-quality software in today's asynchronous world.

History of the Scooter

Published: 2024-04-01 08:53:58

Zoom back in time and explore the fascinating journey of the scooter! While most associate them with the 20th century, their roots go further back.
In the 1860s, a three-wheeled "Velocipede" emerged, paving the way for future scooter designs. Fast forward to 1915, and the "Auto-scoot" arrived - the first true scooter, though it ran on gasoline and didn't gain much traction.
So, the next time you hop on a scooter, remember its rich legacy and the innovative minds that brought it to life! Read more: https://scootize.com/

Understanding TikTok Growth: The Dos And Don’ts Of Views And Followers
Published: 2024-04-01 08:37:57

So you are considering to buy TikTok likes. That is surely a quick way to make yourself more visible and trustworthy on the site. But you shouldn’t forget that there is more to growth than just views and follower success. Let’s go over the dos and don’ts of getting TikTok views and followers to make sure you’re ready to make a purchase.

Do some research

It’s best to do some research before jumping right into buying views and followers. There are various service providers, and some might do shady things that could actually hurt your account over time. Consider companies with good reviews and clear pricing systems.

Don’t Believe Unrealistic Promises

Have you ever come across an ad that sounds too good to be true? Usually, these are the ones that you need to stay away from. If someone says they’ve grown over 20,000 followers in a day, they might not be telling the truth. Trust providers that let you buy TikTok followers and show small but sustainable growth over time.

Give Yourself Reasonable Targets

Do not overestimate what you can gain by buying followers and views. You can buy followers and likes for growth, but don’t be completely dependent on it for your TikTok channel. Be invested in other tactics that help you grow your channel, like making quality content and trying to understand your audience.

Quality content shouldn’t be ignored

TikTok’s success depends on regularly posting high-quality, interesting videos that your audience enjoys. Buying views or followers can’t fix content that nobody wants to watch.

Watch your results carefully

Watch your TikTok analytics closely to see how the views and followers you bought are affecting your channel. Are you noticing more interaction and new followers? Are more people seeing your content? Adjust your plan based on this information to get the best return on investment (ROI).

Connect with your audience

You must be consistent in showing interest in what your audience wants. It would help if you tried making real relationships with your audience and growing your following naturally by interacting with them in a real way and posting interesting content.

Make an investment in your brand

Consider investing in other parts of your TikTok presence besides just followers. For example, you could use content creation tools, work with other creators, or run marketing campaigns when you buy TikTok views. Ultimately, building a strong personal brand can help you keep your followers for a long time.

How to Split Attributes of Same Type in One Row and Convert Them into Multiple Rows

How to Split Attributes of Same Type in One Row and Convert Them into Multiple Rows

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bm7dx1ki6v8fupw8nurp.png)
The actual table is rather wide and here we just use seven columns to do a computing a task. The goal is to split the same types of attributes in one row and put them into multiple rows. Desired result is as follows:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rah0yg11p6ejvn93bbak.png)
Under STEP_NUMBER, we enter values in the form of STEP[n], populate STEP[n]_STATUS values , STEP[n]_START values and STEP[n]_END values to the corresponding columns, and calculate the difference between STEP[n]_END and STEP[n]_START.

Below is SQL solution in SQL Server:

```
SELECT A.ORDER_NUMBER 

      ,B.*

      ,DURATION_IN_DAYS = DATEDIFF(DAY,B.STEP_START,B.STEP_END)

 FROM  TBLORDERS A

 CROSS APPLY ( VALUES ('STEP1',[STEP1_STATUS],[STEP1_START],[STEP1_END])

                     ,('STEP2',[STEP2_STATUS],[STEP2_START],[STEP2_END])

)B (STEP_NUMBER,STEP_STATUS,STEP_START,STEP_END)
```
This is not difficult if we approach it in a natural way of thinking. There are 3n columns after the first column. Every 3 columns correspond to one step, so we just need to insert the step number (STEP[n]), STEP[n]_STATUS, STEP[n]_START, STEP[n]_END, and the difference between the date of STEP[n]_END and that of STEP[n]_START. The dynamic column-to-row/row-to-column transpositions, however, are a long-lasting SQL difficulty. The language cannot use UNPIVOT to achieve the dynamic column-to-row transposition because it does not allow using the non-constant expression as UNPIVOT value. SQL Server offers CROSS APPLY to be able to insert value in the left table into the right table, but, in this case, it is extremely hard to query desired values from the left table as the number of columns cannot be predefined.

 

It is convenient to achieve the above algorithm with the open-source esProc SPL:

SPL is the professional data computing engine. It is designed based on ordered sets, and offers a complete set of set-oriented operations by combining advantages of Java and SQL. It is really easy for it to handle dynamic row-to-column/column-to-row transpositions.

Monetization Eligibility: To monetize your channel, you need to meet certain requirements, including the 4,000 watch hours threshold. By focusing on USA-based views, you ensure that your watch hours count towards this goal, bringing you closer to monetization.

Resolve “Hash sum mismatch” error when running `sudo apt-get update` in Kali linux 2024.1
Tags: linux, webdev
Published: 2024-04-01 08:12:59

Encountering a **Hash sum mismatch** error during the execution of sudo apt-get update in Kali Linux can be attributed to various factors. These factors encompass network issues, repository problems, syncing errors, outdated repositories, package management system anomalies, package corruptions, software upgrades, disk issues, package verification discrepancies, and security measures such as proxy or firewall settings.

![hash sum mismatch](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/k08knw68ilzd1egpvti3.png)

So, I encountered this error and I tried so many possible solutions. These included ensuring a stable internet connection, clearing the apt cache, temporarily disabling the firewall, and exploring other network-related adjustments.

I stumbled upon a solution, which helped solve the problem.
This was how I solved the issue:

Firstly, I paid a visit to [Kali's official mirror site](http://http.kali.org/README.mirrorlist). I scrolled down and I saw something like in the image below.

![kali mirror list](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/f61i6y1cek5boq4esxtt.png)

I needed to view [the closest mirror](http://http.kali.org/README?mirrorlist). And I scrolled down and saw this.

![close mirrors](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bzrgtsyolmosxyoy7uzp.png)

The closest to me seemed to be `http://kali.download/kali/`. So, I then decided to change my mirror link to it. 

**Now, the next question is, how did I view and change my mirror link?.**
Firstly, run `sudo su` in your terminal to switch to the super user mode.
Then, run `nano /etc/apt/sources.list` to access the mirror link. You will see something like this 

![sources.list file](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/be8ytvslk4pgl0aty8h4.png)

Change only the link in the second line to the nearest mirror link you got. As you can see, I already changed it. 
Then `run sudo apt-get update` again. 
I hope this helps.
Thanks.
