how to draw a shape Path

Try this:

var mySolidColor= new SolidColor();
mySolidColor.rgb.hexValue="ff0000";

DrawShape([100, 100], [100, 250], [200, 200], [200, 100]);


function DrawShape() {
    var doc = app.activeDocument;
    var y = arguments.length;
    var i = 0; 
    var lineArray = [];

    for (i = 0; i < y; i++) {
        lineArray[i] = new PathPointInfo;
        lineArray[i].kind = PointKind.CORNERPOINT;
        lineArray[i].anchor = arguments[i];
        lineArray[i].leftDirection = lineArray[i].anchor;
        lineArray[i].rightDirection = lineArray[i].anchor;
    }

    var lineSubPathArray = new SubPathInfo();
    lineSubPathArray.closed = true;
    lineSubPathArray.operation = ShapeOperation.SHAPEADD;
    lineSubPathArray.entireSubPath = lineArray;

    var myPathItem = doc.pathItems.add("myPath", [lineSubPathArray]);

    //myPathItem.fillPath(mySolidColor,ColorBlendMode.NORMAL,100,true,0,true,true);
    //myPathItem.strokePath(ToolType.SHARPEN);
    makeShape ()
    myPathItem.remove();
}
