Comprehension Questions

Question	Answer
How are events / event handlers and this.state connected?	we are changing the state based on an event happening.
What are two ways to do "dynamic styling" with React? When should they be used? When we change the state of a object we can style or when we use a boolean based on input information.
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.	Browser User Input VDom update Dom renders back to browser. We over it in class.
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?	React views are dynamic and react decides when an item should be updated automatically.
What was a challenge you were able to overcome on this assignment?	Understanding the callback function and the use of state. Although it is still a bit new this project allowed me to have a better understanding of these function as well as dynamic styling.

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?	O(n)
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	Two commits? :'(
Comprehension questions	Missed a question!
Functionality
Clicking on litter or nature shows a check or X respectively	Yes, but getting the click to activate is hard, see comment.
Clicking on litter appropriately updates the score	Yes
Under the Hood
JavaScript is well-organized and easy to read	Yes
Functions are named appropriately	Yes
Callback functions are passed to components appropriately	Yes
Overall	Good work on this assignment! Your use of callback functions tells me that the important learning goals for this assignment were met.
