## Hello 👋
In this post, I will show you how to make Lorem Ipsum generator in JS.

This is Part 3 of the 10 JS Project Challenge.

So let's get into it.

First, here is the video tutorial:

### So let's start coding.

First, we need to create three files:

- index.html

- style.css

- home.js

Once we have those files created, we can start coding.

Here is the code for index.html:

```HTML
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Lorem Ipsum</title>

    <!-- styles -->
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <section>
      <div class="center">
      <h3>Lorem Ipsum Generator</h3>
      <form class="lorem-form">
        <label for="amount">Paragraphs:</label>
        <input type="number" name="amount" id="amount" placeholder="5" />
        <button type="submit" class="btn">generate</button>
      </form>
    </div>
      <article class="lorem-text"></article>
    </section>

    <!-- javascript -->
    <script src="app.js"></script>
  </body>
</html>
```
We are just creating a Simple form with Number input and with a button. Then we have a section, where it will be our generated text.

Now, let's move to the styling!

Open style.css and write in that code.

```CSS
@import url('https://fonts.googleapis.com/css2?family=Roboto:ital,wght@0,100;0,300;0,400;0,500;0,700;0,900;1,100;1,300;1,400;1,500;1,700;1,900&display=swap');
*{
    padding: 0;
    margin: 0;
    box-sizing: border-box;
    font-family: 'Roboto', sans-serif;
}


    
.center{
    display: inline-block;
    margin-top: 100px;
    margin-left: 42.5vw;

}

h3{
    font-size: 1.5rem;
    font-weight: bold;
}
article{
    margin: 50px 25px 0 25px;

}
button{
    background-color: skyblue;
    border: none;
    border-radius: 5px;
    padding: 10px;
    margin-left: 15px;
    font-size: 1rem;
    font-weight: bold;
    cursor: pointer;
    transition: 0.3s;
}
button:hover{
    background-color: #00bfff;
}
```

I think the CSS has no explanation here, so let's move to the JavaScript.
In app.js paste this code.

```JAVASCRIPT
const text = [
    `Jelly sweet roll jelly beans biscuit pie macaroon chocolate donut. Carrot cake caramels pie sweet apple pie tiramisu carrot cake. Marzipan marshmallow croissant tootsie roll lollipop.

  ];

  const form = document.querySelector(".lorem-form");
  const amount = document.getElementById('amount');
  const result = document.querySelector('.lorem-text');

  form.addEventListener('submit', (e) => {
    e.preventDefault();
    const value = parseInt( amount.value);
    const random = Math.floor(Math.random() * text.length);
    
    if(isNaN(value) || value < 1 || value > 9) {
      result.innerHTML = `<p class ="result align="center">${text[random]}</p><br>`;
    }
    else{
      let tempText = text.slice(0, value);
      tempText = tempText.map(function(item){
        return `<p class ="result" align ="center">${item}</p><br>`;
      }).join("")
      result.innerHTML = tempText;
    }

  });
```
So, at first we have a text array with Lorem Ipsum Text, so we can grab that text and use it. 
Then we need to declare variables for form, input and result.
Then we are listening to user to click button, and when they clicked it, we are changing the value from original string, to Integer through parseInt( amount.value).

If the value is Nan(user have-not write anything to the input field), or is less than 1 and bigger than 9, we want to randomly generate text through Math.random() - variable random which we declared. 

If the user wrote the correct value, we want to pick text from the array, that is corresponding to the correct value. Then we want to map(pick a corresponding text from array) and return and HTML element with this text. 

And then we want to just print the text using innerHTML. 

And that is. Now you can generate Lorem Ipsum whenever you need it.
