Answer 1

Thank you for your answer, I have the same idea but I wanted to be sure and ask confirmation.

Answer 2

The aim of JavaScript is to make for dynamic web pages THAT'S ALL. If your not adding behaviour don't use JavaScript.
JavaScript controls html and CSS.
What then controls JavaScript.
PHP. Which then relates them to the database which stores the data produced.

Answer 3

Maybe the main difference. The Javascript perforned the operations with such data imedietly in browser in clients computer, and display the results too, imediatly in webpage. It is very quick (when the computing is not heavy). But the Javascript has many limits (with files, databases, etc)
But to PHP, the data are sending over internet to server, there the PHP modul performed them and the whole web page with results sends back to the client computer. So there is a time delay. But, the server is usually a high-performance computer, so the heavy computes run quicker here.And has access into data stores, databases, generation of pictures, password management and many more
So, the asnwer is the simple compute (or checking) make in Javascript, the difficulty in PHP. Many webpages use both.
But there is a one next point of view. Javascript is implemented in all browser, so you can use it (and code in) imedietly for everywhere , But for PHP you have to have a support in web server (as the PHP module). If you want to try it for learning lcally, you would install the web server with PHP module here /like XAMPP)..
