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         


        

Answer 1

No there is no analogous function nor is there any way to get variable names/values for the current context -- only if they are "global" variables on window, which is not recommended. If they are, you could do this:

function compact() {
    var obj = {};
    Array.prototype.forEach.call(arguments, function (elem) {
        obj[elem] = window[elem];
    });
    return obj;
}
