WordCounter

This is a simple class for counting words and calcuating frequencies. Initialise a new counter using new keyword.

import WordCounter from '@javagt/wordcounter'
const counter = new WordCounter()
const other_counter = new WordCounter()

counter.add(['one', 'two', 'three'])

counter.add('two')

other_counter.add('three', 3)

counter.add(other_counter)

console.log(counter.counts)
// { one: 1, two: 2, three: 3 }

console.log(other_counter.counts)
// { three: 2 }
