How is created the . js extension file that is used by the browser in opening web pages?

I’m studying a site already created to understand the operating system of the sites. In the archives of this site, when saving the complete web page, I can find some . js files, and would like to understand how it is created. Can someone help me with that?

Second question: What is the language name of this file?

Third question: This file can be created with Dreamweaver?

JS is the Javascript extension

And yes you can create JS files using any text editor (Dreamweaver, Sublime, Atom, VIM, Notepad, etc.)

And for the files . JS to be called on a page the simplest way is for you to create a file . JS example: js file.

And then in your index.html you can call it that way here

<script src="arquivo.js"></script>

And then your html looks something like

<!DOCTYPE html>
<html>
    <head>
        <script src="arquivo.js"></script>
    </head>
    <body> 
        <h1>Oi Mundo</h1>
    </body>
</html>

NOTE: Just remember that for this to work your.js file and your index.html must be in the root of the same folder.

  • So Vinicius, thank you for your reply.

  • Could you point me somewhere that I can learn the language contained in the . js files? Because I have basic knowledge of html, css and also programming in java, but I’ve never seen anything like this language. Here is a brief excerpt of the text contained in a file . js: ! Function(c,p){"Object"==typeof module&&"Object"==typeof module.Exports? module.Exports=c.Document? p(c,! 0):Function(c) {if(! c.Document)thro w Error("jQuery requires a window with a Document");Return p(c)}:p(c)}

  • A good place to start I think it may be the very training that google is releasing, completely new and innovative: https://google.dev/u/new
