In my opinion, there are several advantages on using JSON and render
it client-side
- Payload: JSON is way smaller than HTML. Specially important if you
are going to be browsed through a 3G connection.
- Server optimization: usually, the server can render JSON faster than
HTML (not in all cases,
What I usually look for in the Profile:
- Identify functions with biggest excl. time and try to optimize them
- Same for functions that are executed a lot of times
- Identify functions with a big difference between total time and
excl. time. It usually means that the function is doing something
I'll try two things:
a) Inspect the Profile output. There is a lot of information there.
Probably your answer is hidden somewhere in that info.
b) Try to disable big portions of the app to get more information on
the problem: is the whole system causing the problems? A specific
module? Try
If I have to choose, I prefer to use 'that' or something more

the 'user' (the programmer using that API). So usually the best option
is to support as many type of arguments (object, separate values...)
as you can. Also, try to be permissive with the order. For example, if
you build a join()
I would add:
To set the prototype of an object, you modify the 'prototype' property
of its constructor function. To get access to the prototype you can
use myFunction.prototype or myInstance.__proto__.
//Constructor function
var myFunction = function() { /*...*/ }
myFunction.prototype.myProperty
