Regular Expression Object Properties

Whenever you create a regular expression, both the RegExp static object and the regular expression object instance you just created are given some properties. Let's take a look at them.

First, let's see what happens to these objects when you first create a regular expression, but haven't done anything with it yet. Say Example 17-1 holds all the code we have.

Example 17-1. Creating a regular expression object
ordString = "How many boards would the Mongols hoard, if
    the Mongol hordes were bored?"
re = /\bmongol\b/ig

First, let's look in Table 17-4 for all the properties the re object now has.
