Is there a function in javascript similar to compact from php?

Question

I found compact function very useful (in php). Here is what it does:

$some_var = \'value\';
$ar = compact(\'some_var\');
//now $ar is array(\'so

If the variables are not in global scope it is still kinda possible but not practical.

function somefunc() {
    var a = 'aaa',
        b = 'bbb';

    var compact = function() {
        var obj = {};
        for (var i = 0; i < arguments.length; i++) {
            var key = arguments[i];
            var value = eval(key);
            obj[key] = value;
        }
        return obj;
    }
    console.log(compact('a', 'b')) // {a:'aaa',b:'bbb'}
}

The good news is ES6 has a new feature that will do just this.

var a=1,b=2;
console.log({a,b}) // {a:1,b:2}
