npm install passive-voicenpm module for detecting passive voice.
Based on this shell script.
``shell`
npm install passive-voice
`javascript
var passive = require('passive-voice');
var problems = passive('He was judged.');
// problems -> [{ index: 3, offset: 10 }]
`
In scientific writing, it's sometimes more reasonable to use passive voice:
> The mixture was heated to 300°C.
Still, it's easy to restate with an active voice passive constructions followed by the
preposition "by."
For example:
> The mixture was heated by the apparatus to 300°C.
Versus:
> The apparatus headed the mixture to 300°C.
For this case, you can pass { by: true } as a second argument to passive to only flag
such constructions as problematic:
`javascript
var passive = require('passive-voice');
var problems = passive('The mixture was heated to 300°C.');
// problems -> []
var problems = passive('The mixture was heated by the apparatus to 300°C.');
// problems -> [{ index: 12, offset: 13 }]
