Property: A property of a type.

Name	Type & Description	Initial
name	string	-

type	string	*
	The type of the property.
hasDefault	boolean	false
	Whether the property has the default value.
default	?(string | boolean | number)	null
	The default value of the property.
optional	boolean	false
	If the property is optional.
args	Array<!Arg>	null
	Function properties can have arguments specified inside of their tags.
isParsedFunction	boolean	false
	Whether the property is a function which was parsed.
aliases	!Array<string>	[]
	What aliases the property has.
static	boolean	false
	When writing externs, this will prevent adding .prototype, e.g., Type.static instead of Type.prototype.static.
examples	!Array<string>	[]
	Examples that have been read.
parsed	_typedefsParser.Type	null
	Whether the property is a function which was parsed.
toTypeScriptFunction	(getLinks: function(!_typedefsParser.Type): string) => string
	If the function was a parsed function, returns TypeScript type. getLinks* function(!_typedefsParser.Type): string: Returns the string with links to other types.

There's a special type of property called an Fn. This one is created when properties are expressed with <fn> or <function> tags. However, when a property is declared using <prop> but with a function as its type, like <prop type="function()">, it's not an Fn. This will probably change in the future.

Fn extends Property: This is a property of a constructor/interface which is a function.

Name	Type & Description	Initial
isConstructor	boolean	false
	If this property of a type is its constructor.
async	boolean	false
	Whether this is an async function.
