Treffer: Data and Decisions.

Data and decision making are fundamental to every "intelligent" program. We'll begin this chapter by looking at how JavaScript understands, or represents, data. This is important because JavaScript works with a number of data types and manipulates data according to its data type. You can generate unexpected results by mismatching data of different types. We'll look at some of the more common data type problems, and you'll see how to convert one type of data to another. [ABSTRACT FROM AUTHOR]
