If you use a global search with .match, JavaScript won't give the capture groups in its array output. As such, you need to do it twice: Once to find the {{...}} pairs, then again to extract the names from within them:

str.match(/{{\s*[\w\.]+\s*}}/g)
   .map(function(x) { return x.match(/[\w\.]+/)[0]; });
