For removed, or added values instead of false an undefined is provided.
Would be nice to provide false instead of undefined.
{ a: 'On the other hand , I love you .',
b: 'Because , I love you .' }
[ { count: 4,
added: undefined,
removed: true,
value: [ 'On', 'the', 'other', 'hand' ] },
{ count: 1,
added: true,
removed: undefined,
value: [ 'Because' ] },
{ count: 5, value: [ ',', 'I', 'love', 'you', '.' ] } ]
