JavaScript uses the RegExp (short for Regular Expression) object to handle pattern matching.

The RegExp object can be created in two different ways.

The first way is to use the RegExp constructor and the keyword new:

var lastName = new RegExp("ABC");

The same functionality could have been accomplished by using a direct assignment:

var lastName = /ABC/;

The forward slash character (/) is used to designate the beginning and end of the pattern.
