What is

A CDATA section is used to mark a section of an XML document, so that the XML parser interprets it only as character data, and not as markup. It comes handy when one XML data need to be embedded within another XML document.

What does CDATA mean in JavaScript?

The term CDATA, meaning character data, is used for distinct, but related, purposes in the markup languages SGML and XML. The term indicates that a certain portion of the document is general character data, rather than non-character data or character data with a more specific, limited structure.

What is the CDATA section in HTML?

A CDATA section contains text that will NOT be parsed by a parser. Tags inside a CDATA section will NOT be treated as markup and entities will not be expanded. The primary purpose is for including material such as XML fragments, without needing to escape all the delimiters.

What does the CDATA stand for?

CDATA stands for character Data and is an XML construct. It lies in between these strings which include data that could mistakenly be interpreted as XML markup. It has no meaning in HTML as it is ignored by the parser.
