Hi . my name is reza and currently living in Iran . Iran is a beautiful country, with hospitable people and rich culture . One of the problems of Iran is high inflation . Because of this the employers from the first-world countries are so willing to work with our developers .

I need a friend from one of the first-world countries like Germany , Canada etc. , who can get client and do necessary negotiations and finally me and my team will do the project .

If you are interested DM me to talk more about details .

The quick guide to getting started in Web Scraping with javaScript

On the Web, we can find an immense amount of very useful data that we can use, but it is disorganized. If we want to take advantage of this, we would need to make a great effort and spend many hours extracting and sort it. A Web Scraper could solve this task.

Its main objectives are:

• Recognize HTML site structures.

• Extract and transform contents.

• To store data.

• Extract data from APIs.

What knowledge do you need to have to get started in web scraping?

There are four key points that we must master to be good web scrapers:

1. Knowledge of web development: Web scrapers work by selecting HTML selectors so, we need to know the HTML structure.

2. Knowing how to work with the DOM: This implies being able to move within its nodes and elements, as well as being able to modify them.

3. Knowing how to use the element inspector of the browsers: To find an element within a website, we use the element inspector and the JavaScript console provided by the browsers.

4. JavaScript and Node js skills: To access the DOM, We use JavaScript code, and we may also need to know how to make GET and POST requests.

As you can see, we will be using JavaScript to develop our scripts. However, more languages allow you to do the scraping, such as PHP and Python. For JavaScript, there is a library called Puppeteerjs that I think is the best for this. In addition, it is developed by and fully supported by Google.

The Web Scraping process

In short, this would be the general process for web scraping:

• Identify the target website.

• Collect the URLs of the pages from which you want to extract data.

• Make requests to these URLs to get the HTML of the page.

• Inspect the HTML returned by the site to collect the data.

• Save the data in a JSON or CSV file or some other structured format.

These would be the main steps to follow for this technique. However, during development, there are many more challenges that need to be solved.

For example, keep the scraper if the design of the website changes, managing proxies to avoid banning problems, the appearance of captchas, etc.

Hi everyone! I’m currently a first year CS student and we have to do a project where we build an online grocery Web App. I started by learning HTML and CSS and did all the design of the web app, but I have no idea what is the next step for me. I know that I should learn how to handle the payment, login and signup conditions, adding items to the basket, etc... but I don’t know if JavaScript is the solution for these problems and if so how should I start learning it? I also saw a lot of people telling me that I should also use react.js for the web app but I don’t know exactly what it is used. I would be grateful if anyone could help me. Thanks in advance

Did you know? You can use a single pipe operator to floor float numbers in javascript.

I suppose to querySelector() is more slowly than getElementById(), because doesn't search just an id, but, search all elements of DOM. Then, getElementById() have less options, therefore, is fastest.

Help me with the answer please, my self peace depends of this.

Is it common for JS files to stop working in VSCode? Instead of being able to call a file in HTML script, I had to paste it in the HTML. Exactly the same code..

window.onload = function() {

var btn = document.querySelectorAll("button");
var taxt = ["woui" , "wowo" , "wiwo" , "wawa"]

for(var b = 0; b < 3 ; b++ ) {

btn[b].addEventListener("click" ,ddo ) ;

} ;

function ddo ()  {

alert(taxt[b])
}
