There is no difference between an array of even numbers and a list of paragraphs returned by document. getElementByTagName(). Is this a fact or a lie? I'd want to know why.

A list of paragraphs returned by document is the same as an array of even integers. getElementByTagName(). Is it true or do you just want to make it up? To put it simply, I'm curious as to the rationale behind it.

Is there anything more outside modifying the application that can be done to keep the page count the same? Evaluate them in light of the economic and technical changes that have occurred recently.

In this project you will use selection lists to store long lists of hypertext links that might overwhelm a page if displayed within a navigation list. The name of a linked page is displayed as the text of a selection list option while the URL is stored as that option's value. By selecting an item from one of the selection list options, the browser will open the web page with that selected URL. To script this action, you will use the event object. One of the properties associated with the event object is as follows: evt.target where evt is the variable name assigned to event object and target is the object that received the event. In this project the target is the option selected by the user from one of the selection lists. The event will be the change event. A preview of the page is shown in Figure 6-39
