 Converts [RDF/JS](http://rdf.js.org/) Terms, Quads and Datasets to N-Triple strings. 
 
 ## Examples
 
 ```javascript
-const rdf = require('@rdfjs/data-model')
-const toNT = require('@rdfjs/to-ntriples')
+import rdf from '@rdfjs/data-model'
+import toNT from '@rdfjs/to-ntriples'
 
 // convert a Term/Literal to a N-Triple string (output: "example"@en)
 console.log(toNT(rdf.literal('example', 'en')))
