How do you create a character class with JavaScript?

What will be an ideal response?

You use acharacter classin a regular expression to treat multiple characters as a single item. You create a character class by enclosing the characters that make up the class within bracket[]metacharacters. Any characters included in a character class represent alternate characters that are allowed in a pattern match. As an example of a simple character class, consider a word with alternative spellings, such as "analyze" (U.S.) or "analyse" (British). The following code uses a character class to check for either spelling of this word by specifying that eithersorzcould be the sixth character in the string:?var wordPattern =/analy[sz]e/;var testResult = wordPattern.test("analyse"); // truetestResult = wordPattern.test("analyze"); // true
