### 10.4 Compound Interest Web Page

Let’s put what you’ve learned into practice with a complete web page that uses a `while` loop and an external JavaScript file. FIGURE 10.3’s Compound Interest web page generates a table of compound interest values for a user-specified number of years. In the figure, note the initial deposit (often referred to as the “principal”) of \$1000 and the interest rate of 10%. Using those values, the table’s year 1 values are calculated as follows. The interest earned is \$1000 × 10% = \$100, and the ending value is \$1000 + \$100 = \$1100. To verify the table values for years 2 through 4, use the prior ending value as the new starting value and apply the same mathematical calculations.
