Is it possible to show in a blog-like webpage the last three posts only with JavaScript?

Question

In order to train myself and improve my knowledge about JavaScript, I am planning to code a function that is able to show inside a simple blog-like HTML webpage the last three posts. These latter should be stored as simple text files with little HTML formatting tags inside a folder and their name should be the date on which the post has been published. Is it possible to do this with JavaScript?
In particular, is it possible to scan a website folder and create an array of file names? Furthermore, is it possible to read a text file and then print it inside the main HTML webpage?
Thanks in advance for your help.

The code included in your answer is not properly clear. Can you please explain it a bit more?

Answer 3

yes you can use DOM and
function x {
document.getElementById("some id")
prompt("something")
var a = input;
document.createElement("p")
p.append(a);
x();
}
this is an example but that is bacically how you would do it
