Boolean
In computer science, a boolean is a logical data type that can have only the values true or false. A boolean is how a programming language lets you represent true and false. Without the ability to represent the boolean values a number of things in a language would no longer work. For example, in JavaScript, an if statement's conditional has to resolve to a boolean value for it to execute at all.  In a JavaScript for loop without it's boolean conditional the loop would never know whether to run it's coding or not.
