SynMustache and RenderJSON and Args param

I try use method:

    /// renders the {{mustache}} template from JSON defined context
    // - the context is given via a JSON object, defined with parameters
    // - you can specify a list of partials via TSynMustachePartials.CreateOwned,
    // a list of Expression Helpers, or a custom {{"English text}} callback
    // - is just a wrapper around Render(_JsonFastFmt())
    // - you can write e.g. with the extended JSON syntax:
    // !   html := mustache.RenderJSON('{name:?,value:?}',[],['Chris',10000]);
    // - set EscapeInvert = true to force {{value}} NOT to escape HTML chars
    // and {{{value}} escaping chars (may be useful e.g. for code generation)
    function RenderJSON(const JSON: RawUTF8; const Args,Params: array of const;
      Partials: TSynMustachePartials=nil; Helpers: TSynMustacheHelpers=nil;
      OnTranslate: TOnStringTranslate=nil;
      EscapeInvert: boolean=false): RawUTF8; overload;

but what is Args parameter? In the above example Args is passed as empty array.

See FormatUTF8:

Re: SynMustache and RenderJSON and Args param

Look closely. See that in the RenderJSON() function the Params parameter is next to the Args parameter:

const Args,Params: array of const;

And Params parameter contains values as in FormatUTF8(). But for what is Args?

Re: SynMustache and RenderJSON and Args param

The doc, as stated by Chaa, is clear on it:

will include Args[] for every % in Format

i.e. they will be included without any JSON escape, whereas Params will make JSON escape.
