CharsetType
About
The charset declaration directive, specified via an 
HTML meta tag or HTTP headers, defines the character encoding used to interpret text in a web document.
If not explicitly declared, browsers attempt to detect the encoding or fall back to defaults, which can lead to incorrect rendering or even security issues in some cases.
JSDoc tags are annotations in 
JavaScript comments beginning with the '@' symbol that are parsed by the JSDoc tool to produce structured API documentation.
They document parameters, return values, types, classes, modules, and cross-references, and are often stripped from production bundles.
