I want to check a collection exists or not. If it exists delete it or if not exist make it.
for example:
if (collectionName) {
delete collectionName;
} else {
make(collectionName);
}
how to do this in mongodb?

The exact details on how to do it depends on the driver your are using.
I am using 3.5.5 version
A driver is language specific, not version specific. Which language, java, js, rust, go?
i am using node js .
Just drop the collection every time, additional access to the collection will create it.
drop(options, callback){Promise}
Drop the collection from the database, removing it permanently. New accesses will create a new collection.
