Count repeating occurences of Bag of Words in JavaScript by reduce

array_count+reduce.js

var r,words="We don't talk anymore\nWe don't talk anymore\nWe don't talk anymore\nLike we used to do\nWe don't love anymore\nWhat was all of it for?\nOh, we don't talk anymore\nLike we used to do\n\nI just heard you found the one you've been looking\nYou've been looking for"
words=words.split(/[\s]+/g);
r=[...words.reduce( (m, v) => m.set(v, (m.get(v) || 0) + 1), new Map() )];
console.log(r)

To add term frequency

r=[...words.reduce( (m, v) => m.set(v, ((m.get(v) || 0) + 1)), new Map() )].map(e=>[e[0],e[1]/words.length])
console.log(r)

To join the array of words in a string of word delimited lines

var r,words="We don't talk anymore\nWe don't talk anymore\nWe don't talk anymore\nLike we used to do\nWe don't love anymore\nWhat was all of it for?\nOh, we don't talk anymore\nLike we used to do\n\nI just heard you found the one you've been looking\nYou've been looking for"
words=words.split(/[\s]+/g);
r=[...words.reduce( (m, v) => m.set(v, (m.get(v) || 0) + 1), new Map() )].join('\n');
console.log(r)

[UPDATE]
Iterate over multiple documents

var docs=["We don't talk anymore\nWe don't talk anymore\nWe don't talk anymore\nLike we used to do\nWe don't love anymore\nWhat was all of it for?\nOh, we don't talk anymore\nLike we used to do\n\nI just heard you found the one you've been looking\nYou've been looking for","I don't like your little games\nDon\'t like your tilted stage\nThe role you made me play\nOf the fool\nNo, I don't like you"]

docs=docs.map(words => words.split(/[\s]+/g) )

var m = new Map()
docs.forEach(words => words.reduce( (m, v) => m.set(v, (m.get(v) || 0) + 1), m ) )
[...m].join("\n")
