Is it possible in JavaScript in a browser, to load an external file (this bit is easy), but given that the external file could be rather large (say 50MB) show a progress indicator of the loading of that file?
i.e I, knowing the serverside size of the file, not knowing the gzip size, I want to say X% of file loaded.
I've not tried anything, I can't find anything to work from let alone find something that suggests its possible.
Problem: Trying to load up a 50MB JavaScript library on demand but show the progress of the loading.

To include an external JavaScript file, we can use the script tag with the attribute src . You've already used the src attribute when using images. The value for the src attribute should be the path to your JavaScript file. This script tag should be included between the <head> tags in your HTML document.
External JavaScript is when the JavaScript Code(script) is written in another file having an extension . js and then we link this file inside the <head> or<body> tag of our HTML file in which the code is to be added.
Use XMLHttpRequest to load the script and monitor its progress. When it's done, eval() it.
