==Lecture Questions==

Here is a consolidated list of lecture questions. Expect these to reappear on the midterm in some form - potentially identical to that below, but also potentially different. Don't memorize the answers, make sure you know the underlying concepts, associated vocabulary, and key details.

===Lecture 3===

# What is the biggest constrain on the performance of web applications? (one word)
# What is the standard that allows web servers to call external programs? (acronym)
# What HTTP command is normally used to request the contents of a page?
# HTTP cookies are only sent to a web server when explicitly requested. (true or false)
# Cookies are normally parsed by client-side JavaScript. (true or false)
# In modern browsers, Which is more of a security risk, browser plug-ins or browser extensions? (plug-ins or extensions)
# NPAPI and "Pepper" are standards for browser plug-ins. (true or false)
# AJAX potentially increases the performance of web servers by offloading computation onto clients. (true or false)

===Lecture 5===

# Every object in JavaScript has a <tt>prototype</tt> property. (true/false)
# The <tt>prototype</tt> property is used when updating and retrieving an object's properties. (true/false)
# The <tt>for in</tt> construct in JavaScript is not so useful because it loops over all of the accessible properties of an object. (true/false)

===Lecture 6===

# In <tt>git</tt>, which is the term used for making a local copy of a remote repository, <tt>branch</tt>, <tt>clone</tt>, or <tt>fork</tt>? (one word)
# In <tt>git</tt>, pushes to the main repository can be dangerous because they can cause file conflicts, add unwanted changes, and cannot be easily undone. (true/false)
# Augmenting a built-in type in JavaScript uses the same syntax as adding a method to a regular object. (true/false)
# Read access to unqualified symbols are resolved by looking at the symbols defined in the inner most function context outward until the global function context is reached. (true/false)
# Read access to object properties are resolved by looking at the object's properties and then by looking at the chain of objects pointed to by the objects on the <tt>prototype</tt> chain. (true/false)

==Lecture 7==

# In the method invocation pattern, a function returns what value if there is no explicit <tt>return</tt> statement? (one word)
# In the constructor invocation pattern, a function returns what value if there is no explicit return statement? (one word)
# In the function invocation pattern, <tt>this</tt> is bound to which object? (one word)
# The apply function invocation pattern does not allow you to set the value of <tt>this</tt>. (true/false)
# The use of <tt>that</tt> is to get around the limitations of the function invocation pattern. (true/false)
# When an exception is thrown in JavaScript with <tt>throw</tt> and handled with a <tt>try/catch</tt> statement, what is the type of the exception message (i.e., the type of the parameter to the <tt>catch</tt> clause)? (one word)
# Current versions of JavaScript are tail recursive. (true/false)

==Lecture 8==

1. For the following, choose one of the following terms and match it with the appropriate description:
node json http html jade stylus express connect jquery ajax css

* client-side JavaScript library for abstracting browser-specific behavior when accessing DOM elements
* standard for encoding data, particularly for transport, using JavaScript-like syntax
* node.js framework for creating web applications
* node.js extensible http server middleware (i.e., supports plugins to add web server functionality)
* html template engine for node
* cleaner CSS syntax for node

2. Sessions impose a strict ordering on HTTP requests in web applications (true/false)

==Lecture 9==

# The form will work fine from the server's perspective even if you remove all the <tt>script</tt> and <tt>link</tt> lines the page's <tt>head</tt>. (true/false)
# This form validates on every keypress. (true/false)
# The form validates only if you enter a pre-defined country. (true/false)
# The "control group" class is used by the core jQuery code. (true/false)
# In the context of FormExample(), $ is a global variable. (true/false)

==Lecture 10==

# Express gives you a static file server by default. (true/false)
# In express, URLs are all automatically resolved by looking for the appropriately named file. (true/false)
# In node, modules declare public functions by assigning them to which object?
# Jade templates only allow you to access a restricted subset of HTML. (true/false)
# In an HTML form, if I want to return a value called "country", which parameter do I set to "country": <tt>id</tt>, <tt>name</tt>, <tt>class</tt>, <tt>for</tt>, or <tt>type</tt>?

	Expect to see code (functions and fragments) that you will have to answer questions about, with at least one client-side example and one server-side (node) one. The best way to study for these is to look back at the code presented in the tutorials.
