AsArray<T>: TArray<T> - supported array types are string, integer, int64, variant.

AsTemplate(const ATemplate: string; const ASeparator: string = ''): string; - render HTML template using key/value pairs. For arrays all elements are processed and combined using ASeparator.

Implicit conversion to string, integer, float, boolean, variant and date/time types is also supported by THtJSONNode.

For JSON objects there are properties for getting values of different type by key:

D[const AName: hstring]: TDateTime

DV[const AName: hstring]: variant - returns Variant containing Date/time or null

S[const AName: hstring]: hstring

V[const AName: hstring]: variant

B[const AName: hstring]: boolean

I[const AName: hstring]: Int64

F[const AName: hstring]: double
