Write and test JavaScript scripts for the two exercises that follow, debug (if necessary). When required to write a function, you must include a script to test the function with at least two different data sets. In all cases, for testing, you must write an HTML file that references the JavaScript file.

• The document must have a paragraph of at least 10 lines of text that describe you. This paragraph must be centered on the page and have space for 20 characters per line only. A light-gray image of yourself must be superimposed over the center of the text as a nested element. Modify this document to add four buttons labeled, respectively, Northwest, Northeast, Southwest, and Southeast. When they're pressed, the buttons must move your image to the specified corner of the text. Initially, your image must appear in the northwest (upper-left) corner of the text. (two files)
• Modify the document described in the previous exercise, using different file names, to make the buttons toggle their respective copies of your image on and off so that, at any time, the document may include none, one, two, three, or four copies of your image. The initial document should have no images shown. (two files)
