prototype - Does JavaScript Object initialization time depends on number of Variables and function? -

ques 1: take more time initialize javascript object if has large number of variables , functions?

ques 2: large javascript(.js) file size performance issue?

for instance: creating javascript object using prototype, sample code below:

function simpleobject(){      // no variables , functions attached } function rootobject(){    var 1 = "one";    var 2 = "two";    .    .    var one_thousand = "one thousand"; } function child_1_object(){     // n number of variables } . . function child_1000_object(){     // n number of variables }  rootobject.prototype.get_child_1_object = function(){    return new child_1_object(); } . . rootobject.prototype.get_child_1000_object = function(){    return new child_1000_object(); } 

all above code in 1 .js file has 10k lines of code(10kloc).
question when create object of rootobject take more time comparing creation of simpleobject?

question one:

making object more complicated, members, functions etc. increase amount of time needed instantiate it. wrote simple jsperf test here prove point: http://jsperf.com/simple-vs-complex-object

one thing note though, you're still creating hundreds of thousands of objects second - it's hardly slow, complex objects.

question two:

large files problematic because of size in terms of client having download them. minifying code this. e.g. http://javascript-minifier.com/
