"description": [
"Objects can be thought of as a key/value storage, like a dictonary. If you have tabular data, you can use an object to \"lookup\" values rather than a <code>switch</code> statement or an <code>if/else</code> chain. This is most useful when you know that your input data is limited to a certain range.",
"Here is an example of a simple reverse alphabet lookup:",
"<blockquote>var alpha = {<br> 1:\"Z\",<br> 2:\"Y\",<br> 3:\"X\",<br>...<br> 4:\"W\",<br> 24:\"C\",<br> 25:\"B\",<br> 26:\"A\"<br>};<br>alpha[2]; // \"Y\"<br>alpha[24]; // \"C\"</blockquote>",

"Convert the switch statement into a lookup table called <code>lookup</code>. Use it to lookup <code>val</code> and return the associated string."
