The raw data that make up the root of data types are called "literals." These are, in effect, literally what they represent themselves to be. Numbers, strings, and Boolean values make up the core set of literals in JavaScript. Little mystery exists with literals, but important differences exist between them. In JavaScript, data types include strings, which are simply quoted characters, numbers, Boolean, Objects and even a type which has no value at all, Null. Since JavaScript is a loosely typed language, you don't neccessarily need to know what type of data every value is (although it certainly helps).

Every piece of data in these categories is known as a value. When a value is referred to outright in a statement, it is called a literal value. For the same reason people are identified by names as opposed to "human" or "person", literal values can be named in order to make repeated reference to them practical, efficent and readable. These names are called variables.

Literals can be of several types. Some of them are:

1. Great tool for effectively communicating ideas to an audience
2. Easy to make last minute changes
3. The undo feature encourages experimentation
4. More attractive; commanded more interest
5. May include animations, sound, video
6. Easy to catalog, store, and recall
7. Great tool for making presenter-free interactive material (e.g. self-learning tutorials)
