New talk-throughs: Clarifying with Comments and Writing Readable Code

We love that we have such an active and creative programming on Khan Academy, and we're inspired daily by seeing the programs that students put out there, and the way they try to help each other. That's why we're putting particular focus in our curriculum on writing code in a way that helps other people learn from it, and we've added 2 new talk-throughs along those lines:

• Clarifying with Comments: How to use multi-line program descriptions and single-line comments to explain tricky parts.
• Readable Code: How to use indentation and whitespace for easy-to-read code.

We hope these lessons will make everyone's programs easier to learn from, and prepare students for a lifetime of clean, clear code.
