It is possbile to read EPS files in JScript?
JScript is not supported by InDesign. I'll kindly assume you meant "Javascript", but be aware that JScript is not Javascript.
It's possible to read any kind of file with Javascript. Any file at all. This snippet
epsFile = File("D:\\auto\\Chapter-3\\fig1.eps");
if (epsFile.open("r") == false)
alert ("Why don't you try an existing file?");
exit(0);
do
someLine = epsFile.readln();
if (someLine.indexOf ('BoundingBox') > 0)
  break;
} while(epsFile.eof == false);
epsFile.close();
reads text lines until it runs out of text lines or encounters one with the exact phrase 'BoundingBox'.
However, Javascript does not automagically know what it's reading. EPSs may contain binary information, so you can't use plain text reading functions. So you need to read binary code -- and for that, you need the exact binary file format of an EPS.
In addition, you need to parse the context of the string 'BoundingBox' as well. It might appear in a text ("This image shows a BoundingBox of ..") or a comment ("%%This image does not have a BoundingBox"), or with extra parameters or parameters missing.
Long story short, "yes, it is possible to read EPS files".
