How is the .js extension file created that is used by the browser when opening web pages?
I am studying a website already created to understand the system of functioning of the sites. In the archives of this site, when saving the complete webpage, I can find some .js files, and I would like to understand how it is created. Can anyone help me with this?
Second question: What is the language name of this file?
Third question: Can this file be created with DreamWeaver?
JS is the extension for JavaScript
And yes you can create JS files using any text editor (DreamWeaver, Sublime, Atom, VIM, Notepad, etc.)
And for .JS files to be called on a page the simplest way is to create an .JS file example: file.js
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: Remember that for this to work your .js file and its index.html must be in the root of the same folder.
