JavaScript objects can be embedded into your web pages to add interest and interactivity to your creations.  There are several free sites available from which you can source interesting tools and objects.  I have included just a couple with this resource.

To start the game simply click on the GO button. Experiment with this to see how you might use such a tool. To add or change the words used you'd go into the source code of the page. Find the following line:

var words = new

Add your words using the existing format...

Loan Calculator
The results of this loan payment calculator are for comparison purposes only. They will be a close approximation of actual loan repayments if available at the terms entered, from a financial institution. This is being provided for you to plan your next loan application. To use, enter values for the Loan Amount, Number of Months for Loan, and the Interest Rate (e.g. 7.25), and click the Calculate button. Clicking the Reset button will clear entered values.  Check out the example in Figure 3, its code is contained in the file LoanCalc.htm.
