I need help with a javascript assignment:

Problem: You have been asked to create a program called payroll_calc.js, that computes and displays paycheck information for employees. The program should compute the gross pay. After it has computed the gross pay, it should deduct three types of income tax withholding federal (at a rate of 15%), state (at 3.4%), and county (at 1.1%) as well as the amount of the employees medical insurance deduction. Finally, the program should total the deductions and calculate the net pay, and display all this information, including the employees name. Use the following values: First Name: Meredith Last Name: Fitch Hours Worked: 40 Hourly Wage Rate: $15.50 Medical Insurance Deduction: $55.00
