Why create a "min" framework?

Question

JavaScript

A lot of javascript developers write their code and minify it like jquery-2.1.4.min.js .
What's the point of this? if now the Internet is very fast, and there is a lot of space on hosting.

Answer 1

When files are transferred there are window sizes.
Let's say 16000 bytes at a time.
There will be a weight of 16001 bytes, then 2 windows will be needed - twice as long.
That's why Gzip and minification are used.
It's easy to do, and the profit is big

Answer 2

so that iPhones with mobile Internet load the lib faster

Answer 3

If you can make the page load faster, you should make it faster. All this directly affects the usability of the site, and hence the loyalty of the user. Moreover, minification practically does not require a programmer's time, there are many automated tools for this.
Look for Amazon research (sort of) on this topic - they explored how page load time affects bounce rates.

Answer 4

This is necessary to optimize the number of requests and protect your code from theft. In the same place not only minification, but also obfuscation often.
