What tool outputs this format? Google Closure compiler?

Question

Looking at some javascript code on someone's website, I see this.

12: [function(t, e, n) {
        ...
    },{}]

And then elsewhere in the file, the function is called this way.

loader: [function(t, e, n) {
    ...
    t(12);
    ...
}, {}]

I assume function 12 is being injected into the function t.

What tool generates code like this? The website functions very well, and I would like to use their ideas (but not their code) to improve my own website.

An obfuscator won't change the structure. And no human wrote this structure. — user2171796, Oct 13 '16 at 15:14
I don't think it's closure-compiler. I believe their parameter names are generally alphabetical starting with `a` when possible. — , Oct 13 '16 at 15:15
Their website works very smoothly. I would like to use the same technology. — user2171796, Oct 23 '16 at 23:43
If you search at Google for this: "loader: [function(t, e, n)" You get a lot of matches. Whatever this technology is, it gets used a lot! — user2171796, Oct 23 '16 at 23:44

It is New Relic stuff. New Relic inserts code to assist them in monitoring.

So it doesn't help me to make a smooth-running website like that of the website I'm looking at. Unless New Relic identifying hotspots has that much effect.
