Javascript string decoding logic translated to Python

The following Javascript code will decode string 91ebf9e9f7a8a2a1a5d1a0a3a7bff2fefc
into an intelligible value:
!function() {
"use strict";
function e(e) {
try {
if ("undefined" == typeof console)
return;
"error"in console ? console.error(e) : console.log(e)
} catch (e) {}
}
function t(e) {
return d.innerHTML = '',
d.childNodes[0].getAttribute("href") || ""
}
function r(e, t) {
var r = e.substr(t, 2);
return parseInt(r, 16)
}
function n(n, c) {
for (var o = "", a = r(n, c), i = c + 2; i < n.length; i += 2) {
var l = r(n, i) ^ a;
o += String.fromCharCode(l)
}
try {
o = decodeURIComponent(escape(o))
} catch (u) {
e(u)
}
return t(o)
}
function c(t) {
for (var r = t.querySelectorAll("a"), c = 0; c < r.length; c++)
try {
var o = r[c]
, a = o.href.indexOf(l);
a > -1 && (o.href = "mailto:" + n(o.href, a + l.length))
} catch (i) {
e(i)
}
}
function o(t) {
for (var r = t.querySelectorAll(u), c = 0; c < r.length; c++)
try {
var o = r[c]
, a = o.parentNode
, i = o.getAttribute(f);
if (i) {
var l = n(i, 0)
, d = document.createTextNode(l);
a.replaceChild(d, o)
}
} catch (h) {
e(h)
}
}
function a(t) {
for (var r = t.querySelectorAll("template"), n = 0; n < r.length; n++)
try {
i(r[n].content)
} catch (c) {
e(c)
}
}
function i(t) {
try {
c(t),
o(t),
a(t)
} catch (r) {
e(r)
}
}
var l = "/cdn-cgi/l/email-protection#"
, u = ".__cf_email__"
, f = "data-cfemail"
, d = document.createElement("div");
i(document),
function() {
var e = document.currentScript || document.scripts[document.scripts.length - 1];
e.parentNode.removeChild(e)
}()
}();
Can anyone explain the actual logic of it, to be able to write it into Python? Or come up with an JS2PY solution of running the code against python-selected values?

You can use js2py module to rewrite automatically the Js code to Python:
import js2py
js_script = """\
function decode(email) {
function r(e, t) {
var r = e.substr(t, 2);
return parseInt(r, 16);
}
function n(n, c) {
for (var o = "", a = r(n, c), i = c + 2; i < n.length; i += 2) {
var l = r(n, i) ^ a;
o += String.fromCharCode(l);
}
return o;
}
var l = "/cdn-cgi/l/email-protection#";
return n(email, email.indexOf(l) + l.length);
}
"""
decoder = js2py.eval_js(js_script)
email = decoder(
"https://journals.sagepub.com/cdn-cgi/l/email-protection#7c0614041a454f4c483c4d4e4a521f1311431f1f414d454c454c494b4a4d3c0d0d521f1311"
)
print(email)
Prints your email.

Resolve a promise after CountUp.js is finished counting

let's say we want to animate a count up from 10 to 100, using CountUp.js we should do something like this:
The question is how can I resolve a promise after the counting has finished.
createMainCountUp(); // initiate once
function createMainCountUp(){
const div = document.createElement("div");
div.id = "percentCounterTarget";
document.body.appendChild(div);
}
promisedFunc(); // this is a function I want
async function promisedFunc() {
console.log('counting has started...');
await Counting(); // I want to resolve this function when counting has finished
console.log('counting has finished!');
}
// here is the main function to start counting
function Counting(){
dial = new CountUp('percentCounterTarget', 10, 100, 4, 5);
dial.start();
//easing dial function
function CountUp(target, startVal, endVal, decimals, duration, options) {
var self = this;
// default options
self.options = {
useEasing: true, // toggle easing
useGrouping: true, // 1,000,000 vs 1000000

};
// extend default options with passed options object
if (options && typeof options === 'object') {
for (var key in self.options) {
if (options.hasOwnProperty(key) && options[key] !== null) {
self.options[key] = options[key];
}
}
}

}
}
Note: the StackOverflow snippet not showing the logs correctly. the code works fine.

Since CountUp.start() can take a callback function, you could create and return a Promise that calls the resolve function once the countdown is finished.
function counting() {
return new Promise((resolve, reject) => {
const dial = new CountUp(...);
dial.start(resolve);
});
}
Edit: Once the countdown is finished CountUp will call the callback function that you pass into .start(). You can see this in the copy of CountUp.js you posted in your snippet - at the comment "whether to continue" in self.count, it calls the callback function once the countdown is finished progressing. We can utilize this in a promise by calling resolve once the countdown is complete.

Function Conflict with Jquery.min.js

currently working on metal website so i need unit conversion tool like in this site
http://www.theunitconverter.com/unit-conversion-widget.html
i try add the code, but its not working.
and its working when i remove this
<script src="https://code.jquery.com/jquery-2.2.1.min.js"></script>
the problem is i need those min.js script for another jquery function.
and i try to add the javascript converter to another file but i couldn't place the correct noconflict function. the js goes like this.

What is it used for? How can such code be written?

That's obfuscated JavaScript.
If you don't know, where it is coming from, it is most likely your site was hacked and this JavaScript is malicious!
What is it used for? How can such code be written?
It is used to hide your code. The reason may be different: Some think they can protect their own code by such things. This, however, is futile as you can see below. Another usecase is for hackers to hide their code from detection. People who often use scripts found on the internet might not see, that this code is invalid and think it is part of some script they wanted to use. Furthermore it hinders the automatic detection of malicious scripts for the same reasons.
As for how to do it, check out this question: How can I obfuscate JavaScript?

EDIT
To the question on how to un-obfuscate:
I just need one tool and that's the development console of a browser, e.g., Firebug.
Then search the code above for the call of eval(). Here it was just called once, sometimes it is called multiple times (even recursive calls can happen). Replace each occurrence of eval() with something like console.log(). That way instead of running the code, it is just printed to the console.
Then run it through an online js-beautifier like http://jsbeautifier.org/ and you have the above code.

How to extract apple's 1 billion countdown? [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.
Closed 12 years ago.
I've been trying to figure it out for hours and i didn't success, This Counter from Apple 1 billion downloads prize. doesn't use flash at all, only javascript and 0-9 images, which makes it really cool. Now after stackoverflow successed to extract google's pacman, can we do that?

Looks like it's a JS counter coupled with CSS.

The hearth of the whole script is this single image: http://images.apple.com/itunes/10-billion-app-countdown/images/filmstrip.png
Now everything should be obvious.
HTML placeholder for a single digit:
<div class="digit-placeholder"></div>
CSS that styles that placeholder:
.digit-placeholder {
/* Dimensions of a single "frame" */
width: 50px;
height: 75px;
background-image: url(...);
background-position: 0 0;
}
To display digit 7 you just have to move background (background-positon property) to the following coordinates: 0 -2800px (that's only an example). To display 8 move it to 0 -3400px.
To create an animation (change from 7 to 8) you just have to move background from -2800 to -3400 with a step of 60 in some period of time (let's say 0.5 second).
All you have to do is to clone that several times (10 times for one billion) and compute that period of time for each digit.

There's a file stored on the apple server which contains a count and a timestamp:
http://www.apple.com/autopush/us/itunes/includes/countdown.inc
That should give you a rough count.

Before I go to bed:
var number = '';
$('.digitImage').each(function(i) {
number += Math.abs($(this).position().top) / 618;
});
console.log(+number);
Now how long did that take? 3 minutes trying to figure out how do install a bookmarklet in chrome for injecting jQuery... 5 more minutes to get it working.
