Is it possible to save JS code changed during debugging?

Question

JavaScript

Is it possible when debugging js code to change it and save the changes.
For example,
Change the function that should fire on page load, => Save => Reload => Debug the modified function before reloading.
Why these movements? There is no permanent access to the code on the server. Browser only.

Link the file from the site to the local one. All changes are duplicated in it, and when the page is updated, the modified copy is used.

And also resource override allows you to replace any files on the fly.
