What is the meaning of CDATA

Answer 1

• Why CDATA sections? CDATA sections tell the XML parser to read the characters without interpreting them as element or entity markup.
• Why leading // marks? We introduce the CDATA opening and closing tags with // marks, so the JavaScript parser ignores the CDATA tags.
• Why .cshtml but not .html? The .cshtml pages, which ASP.NET MVC uses, are XML based whereas .html pages are not.
