Congratulations! You're submitting your assignment!

Comprehension Questions

Question	Answer
How are events / event handlers and this.state connected?
What are two ways to do "dynamic styling" with React? When should they be used?
Much like Rails works with the HTTP request->response cycle, React works with the browser's input->output cycle. Describe React's cycle from receiving user input to outputting different page content.
Compare how React and Rails' views differ. Given different circumstances, these systems have different goals. How does this impact on their design and how we are supposed to use them?
What was a challenge you were able to overcome on this assignment?

CS Fundamentals Questions

Question	Answer
Consider the code on the first few lines of App.render (it starts with this.state.items.map). What is the Big-O time complexity of this code, where n is the number of active game items?
What part of React might benefit most from the use of specific data structure and algorithms?
Consider what happens when React processes a state change from setState -- it must re-render all of the components that now have different content because of that change. What kind of data structure are the components in, and what sort of algorithms would be appropriate for React's code to "traverse" those components? Speculate wildly about what the Big-O time complexity of that code might be.

What We're Looking For

Feature	Feedback
Core Requirements
Git hygiene	2 commits.
Comprehension questions	Blank
Functionality
Clicking on litter or nature shows a check or X respectively	Yes
Clicking on litter appropriately updates the score	No score updates.
Under the Hood
JavaScript is well-organized and easy to read	Yes
Functions are named appropriately	Yes
Callback functions are passed to components appropriately	Close! You gave a wrong name, otherwise the project would be working perfectly!
Overall	This was super close, and it looks like you have the pattern for passing methods down to components in hand, if not perfect yet.

So, your naming convention is wrong here, keeping your click handler from being passed down. this.onClickHandler doesn't exist. This is where we pass the function down to the component, so we want to use this.onItemClick instead.
