Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.
Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.
This text now lives at https://github.com/MarcDiethelm/contributing/blob/master/README.md. I turned it into a Github repo so you can, you know, contribute to it by making pull requests.
If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on Github, new technologies and and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.
Check your understanding so far. Make sure to play the part of Engine and have a "conversation" with the Scope:
function foo(a) {
var b = a;
return a + b;
}
var c = foo( 2 );
Identify all the LHS look-ups (there are 3!).

| - Write a program to calculate the total price of your phone purchase. You will keep purchasing phones (hint: loop!) until you run out of money in your bank account. You'll also buy accessories for each phone as long as your purchase amount is below your mental spending threshold. | |
| - After you've calculated your purchase amount, add in the tax, then print out the calculated purchase amount, properly formatted. | |
| - Finally, check the amount against your bank account balance to see if you can afford it or not. | |
| - You should set up some constants for the "tax rate," "phone price," "accessory price," and "spending threshold," as well as a variable for your "bank account balance."" | |
| - You should define functions for calculating the tax and for formatting the price with a "$" and rounding to two decimal places. | |
| - Bonus Challenge: Try to incorporate input into this program, perhaps with the prompt(..) covered in "Input" earlier. You may prompt the user for their bank account balance, for example. Have fun and be creat |
