Types of Data

Work with Numbers, Strings, Dates, Currency, and More

This chapter discusses basic JSL data types:

• Numbers and strings

• Paths, which are a special type of string

• Dates and times, which can be either special numbers or special strings

• Currency

• Hexadecimal values and blobs

At the end of the chapter are two sections that show more advanced methods of interacting with strings and pattern matching with regular expressions.
