====== Primitive Data Types ====== JavaScript has five primitive data types: * Undefined * Null * Boolean * Number * String ===== Examples ===== A Boolean is a logical entity that consists of either a true or a false value. An example of one is: var BooleanValue = true; A Number is a set of numerical digits that represent a number. Through this tutorial, we'll only use base-10 numbers. An example: var NumericalValue = 354; A String is a set of zero or more characters. An example: var StringValue = "This is a String";
