JavaScript Homework 1
Question 1: Trace the execution of the following JavaScript code. For each of the document.write statements, list the output that would be displayed.
value1 = 14;
value2 = 8 - (3 + 2);
document.write("value1 = " + value1 + ", value2 = " + value2);
x = 99 / 2;
y = 99 % 2;
z = 99 % 3;
document.write("x = " + x + ", y = " + y + ", z = " + z);
x = 2 * 3 * 4 * 5;
document.write("x = " + x);

Question 2: Trace the execution of the following JavaScript code. For each of the document.write statements, list the output that would be displayed. Assume that the user enters the value 1024 at the prompt.
x = prompt("Enter a number", "");
document.write("Double " + x + " is " + (2 * x));
document.write("Double " + x + " is " + (x + x));
x = parseFloat(x);
document.write("Double " + x + " is " + (x + x));

Program Part 1:
Create a new web page called incomeTax.html. This page will ask the user for their income, and based on that income, calculate the amount of income tax they owe.
Use a prompt box to get the user's income.
Use if/else statements to calculate the amount of tax they owe, using the following rates:
Income
Tax Rate
$0 - $49,999.99 15%
$50,000 - $99,999.99 $7,500 + (20% of income > $50,000)
$100,000+ $17,500 + (25% of income > $100,000)
Display their income, tax rate, and amount of tax they owe. Use document.write() statements to do this.
Program Part 2:
Modify the above program to include a loop to allow the user to continue to calculate the tax for other incomes, until the user chooses to quit. What type of loop should you use for this?
