How to pass variable name as collection name for mongo db in nodejs

Question

I am using node js and mongo db and I want to pass a variable to collections

var id = "someid";
db.collection(id).insert("some json data");

If I did like this it is giving me an error as collection name must be a string.

You can create variable using var for collection name

var colName = "mytest"

and then execute all the operations on collections as below:

db[colName].find()
db[colName].rename("newName")

etc. This will help you keep your collection name dynamic and can even update it keeping your commands same.

Hope this helps!
