This library implements an array diff application algorithm that can apply a diff on part of an array to the whole. Given a complete array, a subset of that array, and a changed version of that subset, this algoritm will apply all the changes betweent the previous and new subset to the complete array.
e.g.
const complete = [1,2,3,4]
const subset = [3,4]
const change = [4,5]
const updated = applyValues(complete, subset, change)
// => [1,2,4,5]
