in Chapter 4 - Adanced CRUD the Video in Lecture: Array Operators states at ~00:30 the following:
$push - Turns a field into an array field if it previously was of a different type.
Doesn’t this confliect with reference documentation: https://docs.mongodb.com/manual/reference/operator/update/push/
If the field is not an array, the operation will fail.
Am i missing something?
