#levelup-iterator Use the async iterator pattern used in LevelDown in LevelUp.
Async iterators can conveniently used with the async-iterators library.
var levelup = require('levelup')
var createIterator = require('levelup-iterator')
var iterators = require('async-iterators')
var db = levelup('test')
var iterator = createIterator(db, {start: 'b'})
iterators.forEach(iterator, function(err, entry) {
console.log(entry)
}, function() {
console.log('end')
})You can pass in all options to createIterator(db, [options]) that are used in LevelUp's db.createReadStream([options]).
