+# CauseEffect
+
+Patterns are integral to software engineering and represent potentially
+reusable components in program logic. However, patterns aren't used only
+for program logic, they are exist in other domains such as DevOps, user
+support, and the user interface.
+
+A common user interface pattern is to summarize data in one section of a page 
+that consists of some type of list (like text, images, or icons) that describes
+or categorizes a set of data. When a list item is clicked, the detailed data
+behind it is displayed in an adjacent pane on the page. 
+
+For example, on a real estate site clicking an address in a list of properties
+for sale displays the details about the property in another part of the 
+page.
+
+This challenge requires that the developer implementing it follow these
+constraints:
+
+- You are responsible for creating your own test data. Use a hardcoded 
+Javascript object to define your test data (see below).
+- Use only native HTML/CSS/Javascript in your first version of this app
+- You may use other packages or libraries when implementing subsequent 
+versions.
+
+## User Stories
+
+-   [ ] User can see a list of person names arranged vertically in a summary
+pane on the page.
+-   [ ] User can click on a name in the list to update an adjacent pane on the
+page with that individuals full name, address, telephone number, and 
+birthday.
+-   [ ] User can click on another name in the list to refresh the detail pane
+with that individuals information.
+
+## Bonus features
+
+-   [ ] User can see the person name in the summary pane highlighted when the
+cursor is hovered over it.
+-   [ ] User can see the person name in the summary pane highlighted
+using a selection effect (color, size, etc.) when it is clicked. This is a
+different effect from the hover effect
+-   [ ] User can see the selection effect removed from a name in the summary
+list when a new name is clicked.
+
+## Useful links and resources
+
+- [DOM Events](https://developer.mozilla.org/en-US/docs/Web/API/Event)
+- Consider defining your test data in a JavaScript object having a format
+such as this:
+```
+const people = [
+  {name: "...", street: "...", city: "...", state: "...", country: "...", telephone: "...", birthday: "..."},
+  .
+  .
+  .
+  {name: "...", street: "...", city: "...", state: "...", country: "...", telephone: "...", birthday: "..."}
+];
+```
+
+## Example projects
+
+Checkout the interaction between the Navigation items on the left hand side
+of the page and the main body of the page on the [Javascript MDN site](https://developer.mozilla.org/en-US/docs/Web/JavaScript)
