Learn How to Download Music With JS106

Introduction

Downloading music from the web can be a convenient way to build your own music library. However, not all websites allow you to download music directly. This is where JavaScript (JS) comes in.

JS is a programming language that can be used to manipulate web pages. This includes downloading files, such as music files. In this tutorial, we will show you how to use JS to download music from the web.

Step 1: Find a Music File

The first step is to find a music file that you want to download. There are many websites that offer free music downloads, such as SoundCloud and Bandcamp.

Once you have found a music file that you want to download, right-click on the link and select "Copy Link Address". This will copy the URL of the music file to your clipboard.

Step 2: Create a New JS File

Now that you have the URL of the music file, you need to create a new JS file. You can use any text editor to create a JS file, such as Notepad or Sublime Text.

Once you have created a new JS file, save it with a .js extension. For example, you could save the file as "".

Step 3: Write the JS Code

Now that you have a new JS file, you need to write the code to download the music file. Here is an example of a JS script that you can use:```
const url = "/music.mp3";
const filename = "music.mp3";
const request = new XMLHttpRequest();
("GET", url, true);
= "blob";
= function() {
if ( === 200) {
const blob = ;
const link = ("a");
= (blob);
= filename;
(link);
();
}
};
();
```

This script will create a new XMLHttpRequest object and use it to send a GET request to the URL of the music file. The responseType property is set to "blob", which means that the response will be a Blob object. The onload event handler is called when the request is complete.

In the onload event handler, the status code of the request is checked. If the status code is 200, then the response is a Blob object. The Blob object is then used to create a new link element. The href attribute of the link element is set to the URL of the Blob object. The download attribute of the link element is set to the filename of the music file. The link element is then added to the body of the document and clicked.

Step 4: Run the JS Code

Once you have written the JS code, you need to run it. You can do this by opening the JS file in a web browser. The JS code will be executed and the music file will be downloaded.

Conclusion

In this tutorial, we showed you how to use JS to download music from the web. This is a convenient way to build your own music library. You can use the JS code we provided in this tutorial to download any music file that you want.
