Comprehension Questions

Question	Answer
How do Backbone Views help structure your code?	Views create more structure and organization to the code. Each view is given a domain on the DOM that it is responsible for rendering and a model or collection that it can listen to for changes that might warrant a re-rendering of the elements in that section of the page. Views also allow us to listen and trigger events for activity on specific parts of the page, instead of having event listeners in app.js that are listening to all parts of the page at all times.
Did you use jQuery directly in your Views? How, and why?	I use a jQuery like selector via ‘this.$’. My understanding is that we don’t use jQuery directly in the view, but instead, we can assign it an ‘$el’ attribute to specify which part of the DOM this View is responsible for, and then use ‘this.$’ to specify a specific part of that element we want to target.
What was an example of an event you triggered? Why did you need to trigger it?	I triggered a ‘newTrade’ event after we buy or sell a quote, and after an open order is successfully placed. I had to trigger it in the event bus because I decided to create a separate model, view, and collection for Trades. Because buying quotes and fulfilling an Open Order happened in different views, models, and collections, I needed to trigger the event in the bus to notify the Trade model and views that there is a newTrade object to add to our Trade collection, and to render the new trade in the view for Trade History
In what was is unit testing in JavaScript similar to unit testing in Ruby? In what ways is it different?	we can still use blocks, describe, and if statements to test specific, modular features of our code.

Feature	Feedback
Core Requirements
Git hygiene	❇️ good professional commit messages
Comprehension questions	x
Organization
Models and collections are defined in separate files	x
Code that relies on the DOM is located in or called by $(document).ready	x
Functionality
Quote prices change when clicking Buy and Sell	x
The Trade History updates when buying and selling a quote	x
A user can create an open order using the Order Entry Form	x
An open order removes itself from the open orders and updates the Trade History when fulfilled	x
General
Has separate views for different parts of the app	x

Practices good standards for views (ES6 syntax, doesn't directly use jQuery, returns this in render)	x
Error handling for the Order Entry Form	x
Testing
Has unit tests for models	When I run the tests, the validation tests fail?

Overall, good work! Event-driven programming is always interesting, especially in contrast with the message-driven programming we've done otherwise. Keep in mind that event-driven is not the only solution available. Otherwise, great job!

ps: I like the touch of the border colors; it made it easier for me to grade ;)
