Comparing Mongoose Object Ids

Forget about nonsense like this in order to compare two Mongoose Ids

if (val.user.toString() === submissionDoc.owner._id.toString()){
	//do stuff
}

Use a built in Mongoose function instead!

if (val.user.equals(submissionDoc.owner._id)){
	//do stuff
}

Or don’t, be convoluted, but before you decide on that check the Zen of Python and see if you can be swayed ;)
