Create Save to folder if it does not exist

Question

I have a script that will save a file to a folder up one level.  In other words if the original file was in client/jpg I wanted it saved in client/digipics.  The client folder will always have a different name.
I want to add code that will create the "digipics" folder if it does not exist.  Here is what I have so far that works as long as I have the "digipics" folder already created:
#target photoshop
var AD = app.activeDocument;
var imgName = AD.name;
var CurrentFolder = activeDocument.path;
var parentFolder = decodeURI(activeDocument.path.parent);
// Write file up one level into "digipics"
saveFile = new File(parentFolder + '/' + "digipics" + "/" + imgName)
saveOptions = new JPEGSaveOptions();
saveOptions.embedColorProfile = true;
saveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
saveOptions.matte = MatteType.NONE;
saveOptions.quality = 8;
AD.saveAs(saveFile, saveOptions, true,Extension.LOWERCASE);
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
What code can I add as an IF statemnt incase I forget to create the folder first.  It would create the folder then save to it.

#target photoshop
var AD = app.activeDocument;
var imgName = AD.name;
var CurrentFolder = activeDocument.path;
var parentFolder = decodeURI(activeDocument.path.parent);
var digiFolder = new Folder(parentFolder + '/' + "digipics");
if (digiFolder.exists == false) digiFolder.create();
// Write file up one level into "digipics"
saveFile = new File(digiFolder + "/" + imgName)
saveOptions = new JPEGSaveOptions();
saveOptions.embedColorProfile = true;
saveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
saveOptions.matte = MatteType.NONE;
saveOptions.quality = 8;
AD.saveAs(saveFile, saveOptions, true,Extension.LOWERCASE);
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
Should do the job…
