Quick Start to First App

The quick starts have been really popular. @BillWagner and I had a quick chat on next steps. What kind of apps can we teach someone to build in the browser? We came up with a few ideas but ideas but, we would appreciate your input. Please remember that users are coming from the C# quick starts and have basic understanding of the following topics:

Declaring and using variables
Working with strings
Numbers in C#
Branches and loops
Interpolated strings
List and collections

What's about to count all digit symbols in a given string?

Build a calculator. Expand it to be a scientific calculator. Give it a programmer mode so calculating in hex and binary. Expand it to record the steps in your calculation. Allow it to unwind back through that history, undoing parts of the calculation. Allow it to store calculations. Introduce variables into the calculations that have to be entered when the calculation is replayed. Perhaps end up with something that is a full on programmable calculator.

An app that group list of grocery to a summary, calculate the total price, and give discount if total exceed certain amount.

a, b, c, a, d, d, d -> 2 a, 1 b, 1 c, 3 d

Basic calculator can be nice. Small, easy to learn, easy to solve problems.

But thinking to build a "specific" app, I think it would be better to have interactive windows like Khan Academy. First you watch the introduction video, then you interact with the same window to solve a specific problem after you learn it.

After that, small exercises would be nice. Such an examples can be found on ProjectEuler, Hackerrank etc. For example, reverse a string, seperate a sentences based on bucket size words, count vowels in a string.
