Notes
- A word's appearance in a sentence does not necessarily imply a positive or negative opinion. See Liu (2010).
- The list includes misspelled words. Their presence is intentional, as such misspellings frequently occur in social media content.
Examples
var floor = require( '@stdlib/math/base/special/floor' );

var list = words();
var len = list.length;
var idx;
