A sequence of characters in the code that identifies a variable, function, or property.
In JavaScript, identifiers can contain only alphanumeric characters (or "$" or "_"), and may not start with a digit. An identifier differs from a string in that a string is data, while an identifier is part of the code. In JavaScript, there is no way to convert identifiers to strings, but sometimes it is possible to parse strings into identifiers.
