Assignment 6 -Intro to programming javascript

MIT 153 – Assignment #6 This assignment requires you to use a separate data file names Asgn6Data.js. This is an external JavaScript file can be “imported” into your Web page by putting the following tags in the “head” section: <script type=”text/javascript” src=”Asgn6Data.js”></script> This file declares a number of arrays and fills them with data. Open the file in a text editor and inspect the data. All of these variables and values will now be available inside your page. (DO NOT try to declare these variables in your code – once you have inserted the above tags these variables are already a part of your page.) Write a program that will use an array to accumulate the total sales by department number as well as an overall total. A sample output is shown below. Note: the department numbers range from one to ten. Use an array of size ten to hold the totals and display the names of the departments from the departNames array provided in the file.

Automotive	18.36
