Is it possible to convert an array in JavaScript into a function argument sequence? Example:

run({ render: [ 10, 20, 200, 200 ] });



function run(calls) {

  var app = .... // app is retrieved from storage

  for (func in calls) {

    // What should happen in the next line?

    var args = ....(calls[func]);

    app[func](args);  // This is equivalent to app.render(10, 20, 200, 200);

  }

}
