Official "Loading reCAPTCHA asynchronously" does not work

[Benjaminhu]

Official "Loading reCAPTCHA asynchronously" does not work:

Uncaught TypeError: grecaptcha.render is not a function

https://jsfiddle.net/657b1gso/

The problem:

...
  grecaptcha.ready = function(cb){
    if(typeof grecaptcha === 'undefined') {  // <- never be undefined
...

I am also experiencing this issue with the code sample

We ran into this issue as well: the code doesn't work as published!

It's strange, I'm not sure what situation or problem they may have wanted to solve or address via that logic, but it isn't correct as-is. I wonder how many sites around the internet are broken in a subtle way because of that snippet in the docs? 🤔

Here's the implementation we are using to accomplish this:

if (typeof grecaptcha === 'undefined') {
	grecaptcha = {
		ready: callback => {
			const c = '___grecaptcha_cfg';
			window[c] = window[c] || {};
			(window[c].fns = window[c].fns || []).push(callback);
		}
	};
}

The documentation has been updated and it seems like this issue is fixed now.
