javascript - mongodb native driver get collection names without database name -

how can collection names without database name mongodb native driver nodejs?

db.collectionnames(function(err, collections) {       if (err) {         log.error(err);       } else {         log.info(collections);       }     }); 

this code returns this:

databasename.collection1, databasename.collection2, databasename.collection3

but want names: collection1, collection2, collection3

the exact structure of response sub-document "name" key in array:

[   { name: 'test.cursors' },   { name: 'test.episodes' },   { name: 'test.zips' },   { name: 'test.scripts' } ] 

so use map regex replace:

db.collectionnames(function(err, collections) {    console.log(     collections.map(function(x) {       return x.name.replace(/^([^.]*)./,"");     })   );  }); 

and strip out first . database prefix. in case have collection names . in them.
