Given a table represented as a javascript array of objects, I would like create a list of unique values for a specific property.var table = [  {    a:1,    b:2  },  {    a:2,    b:3  },  {    a:1,    b:4  }];var groups = _.groupBy(table, a);var array = [];_.forOwn(groups, function(value, key){  array.push(key);});console.log(array);<script src=https://cdnjs.cloudflare.com/ajax/libs/lodash.js/3.10.1/lodash.min.js></script>Check your consoleThe problems with this code is that the groupBy keep track of the values, which I really don't care about, and I need to iterate over the entire list generated by group again so I can yank out the keys. It seems pretty inefficient to me and Im wondering if there is a smarter way to do this without reinventing the wheel (or perhaps if I should just bite the bullet and reinvent the wheel).
