Let's say i put a limit and skip on the MongoDB query...I want to know the total results if there was not a limit on there.
Of course, I could do this the shitty way...which is to query twice.

MongoDB count() Method – db. Collection. count() The count() method counts the number of documents that match the selection criteria.
The limit() function in MongoDB is used to specify the maximum number of results to be returned. Only one parameter is required for this function.to return the number of the desired result. Sometimes it is required to return a certain number of results after a certain number of documents. The skip() can do this job.
MongoDB $count AggregationThe MongoDB $count operator allows us to pass a document to the next phase of the aggregation pipeline that contains a count of the documents. There a couple of important things to note about this syntax: First, we invoke the $count operator and then specify the string.
In MongoDB the default behavior of count() is to ignore skip and limit and count the number of results in the entire original query. So running count will give you exactly what you want.
Passing a Boolean true to count or calling size instead would give you a count WITH skip or limit.
