Please how can someone update web pages using code

Question

Update web pages

Answer 1

Using AJAX(Asynchronous Javascript And XML), websites can send and retrieve data from a server or other websites asynchronously (in the background) without interfering with the presentation.
This allows web pages and web applications, to change content dynamically without needing to reload the entire page.
