## Description
|

|
|
<section id='description'>
|
||
|
|
Sometimes you will need to build a string, <a href="https://en.wikipedia.org/wiki/Mad_Libs" target="_blank">Mad Libs</a> style. By using the concatenation operator (<code>+</code>), you can insert one or more variables into a string you're building.
