Long Live CoffeeScript and Long Live ES6

Long Live CoffeeScript and Long Live ES6

Clearly ES6 is a huge improvement over ES5, and tools like [6to5][] allow us to use these cool features now. I was reading [Replace CoffeeScript with ES6][replace coffeescript] by [Blake Williams][] and thought it was a great summary of how ES6 solves many of the same problems that CoffeeScript solves; however I'd like to comment on a few of Blake's points and talk about why I'll be sticking with CoffeeScript.

Classes

Classes in ES6 (like many of the syntax changes in ES6) are very similar to the CoffeeScript equivalent. To support browsers that are not fully ES5 compliant (e.g. IE8-), however, we still can't really use getters/setters, so ignoring these the comparison is:

* absolute - top left is starting point
* relative - same as absolute, but starting from static position; Parent elements remain as they are.

One of my favorite Drupal-specific interceptions: if you are a president ...

$role_term = taxonomy_term_load($role[0]['tid']);
$is_president = !$role_term ? FALSE : _commissioner_uuid_is('president', $role_term->uuid);
if ($is_president && $group->label == 'Responsibilities') {
$group->label = t('Role');
