Good blog post on promises: https://developers.google.com/web/fundamentals/getting-started/primers/promises

• A built-in part of the JS language since ES6
• Native in most browsers now (except IE11 and older, Android 4.4 and older)
• Available everywhere using JS implementation
• http://caniuse.com/#search=promises

Hybrid apps in 2014

• What is is like to build hybrid apps in 2014?
• How does it differ from mobile development in 2014?

The tools:

• Webviews
  • WebView not necessairly the same as the built-in browser on the device.
• Apache Cordova

Keybase proof

I hereby claim:

• I am eoinkelly on github.
• I am eoinkelly (https://keybase.io/eoinkelly) on keybase.
• I have a public key whose fingerprint is 05FB 2362 B986 574E 8E04 10BD 6491 A52A CC5D AABC

To claim this, I am signing this object:

eoinkelly

##
# id must be the id attribute of the editor instance (without the #) e.g.
#     <textarea id="foo" ...></textarea>
# would be filled in by calling
#     tinymce_fill_in 'foo', 'some stuff'
#
def tinymce_fill_in(id, val)
  # wait until the TinyMCE editor instance is ready. This is required for cases
  # where the editor is loaded via XHR.
  sleep 0.5 until page.evaluate_script("tinyMCE.get('#{id}') !== null")

// I am confused about how you can use `call` without supplying an object for `this`
// The docs don't indicate that you can: 
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call

var funny = function (a) { return (a + 3); }
funny(3);           // 6
funny.call({},3);   // 6
funny.call(3);      // NaN  // (as expected)
