PS Scripting: JavaScript Document.SaveAs TiffSaveOptions

May you say where in Data Browser tab of ESTK I can find tiffSaveOptions, or what to do to see it there?

I do not know JavaScript so I steal code.  Who do I steal from?  One source is from Adobe Photoshop.   It may not be the greatest idea Photoshop has a lot of bugs.  However, in the case Adobe script export layers to files seem to have Save As code for many image file types with options for the a file type.  I do not save Tiff files so here I would need the be the thief
