Heavily-scripted data entry forms that expand on-the-fly as the user enters new data make life easier for the user. However, it can be hell for a developer to devise a method for the representation and submission of data with arbitrary length and depth.
A logical thing to do seems to be to take an object-oriented approach to represent all client-side data as one or multiple JavaScript objects....

}
Even if the string literal "MAGIC_PREFIX_" is not due to change in a life time, it makes the code more prone to human error and harder to read when the length of the string is hand-counted and hard-coded as a separate entity (13 in...

I recall the tedious process of manual tweening to create the individual frames (by calculating the angle and position differences and dividing them by the number of frames) using Freehand.

function MyClassA() {
}
var obj = new Object();
var arr = new Array();
var myobj = new MyClassA();
document.write(typeof(obj) +...
