1.  Is it similar to React, which is also a javaScript library?
2. Is this how user-specific information is populated when logging into a website with assitence from the back end?
3. On the topic of accessibility, when creating/adding new elements to the page, good semantic HTMl would be key, but what other accessibility factors could we include? The "role" attribute?
4. How does using $() return a jQuery object? Does it use a factory function that gathers all the properties of the selected element?
5. Does the jQuery library change or get updated often?
