Comment (by TV productions):

 How it works:
 * It uses the Po/Mo files that are parsed in PHP to generate a structure
 that the javascript functions will use.
 * When enqueueing a script that needs some of the js gettext functions,
 you have to call `wp_js_gettext_enable` with the textdomains you want.

 * All translations (for PHP and JS) in one Po/Mo file for each textdomain.
 * As much as possible consistency between PHP and JS.

 Possible drawbacks:
 * All the translated strings are always loaded: for the current core
 translations (textdomain 'default') is that about a 600KB script.
 * There has to be a JS function like sprintf to parse `%s`, `%d`, `%1$s`,
 etc. Possible starting point: [sprintf for
 * It uses the standard plural expression from gettext (for example
 `n!=1`), but this code is executed in js and maybe a security issue. the
 plural expression is currently filtered by a regular expression that
 removes all charters that shouldn't be in a plural expression, but it
 still is a bit tricky.

 This are my thoughts about it: I appreciate it when you share yours. If
 you have any solutions for the drawbacks or just have some fancy idea:
 share it and/or create a pull request!
