Additional notes:
1) The complement of the empty set is the whole set U ( universe).
Complement of {} = U.
2) Subtracting works even when there is no overlap: it is just the whole first set, since there is nothing to subtract.
A - B = A, when A intersect B = {}.
3) A - {} = A.
4) A union {} = A.
5) A intersect {} = {}
6) {} - A = {}

    JavaScript:


    Easy to get started: just write a program in text (samples follow) and save as .htm. Then open with a browser.
    JS is still the most popular language among developers.

    Below are some easy sample programs to get started! To run the code, click the link. To see the code, add this term to the beginning of each URL: view-source:
    ...or after clicking on a linked program then click on tools and developer tools, and then look at elements (in Chrome) or script (in Explorer).

    This one just prints Hello World to the screen and the console. To see the latter, open tools and developer tools, and then look at console.

    This one calculates the value of sin(x)/x for any input.

    This one animates sin(x)/x with zoomability.

    For really learning JavaScript I recommend the free book Eloquent JavaScript by Marijn Haverbeke.

    Here is a great tutorial by Matt Mongeau for writing javascript games.
    Here's the Pvs.P Awesome Pong variation Will F. and I wrote using Mr. Mongeau's code:
    top player uses a-w-s-d, bottom uses arrows; first to 10 points wins.
    Here's Will's Mouse-over mole game.
    Mouse over the mole to gain as many points as you can in 30 seconds. My high score is 229.
