Change Addition

[suni-masuno]

Feature Request: It seems reasonable (and fits my case) to take an array of changes and sum them into one final change. With some moderate effort I could (and might) write this myself, but it seems like a natural fit for the project itself. My inclination is something like sumChanges([change1,change2,change3...changen])~~>totalChange so that I can look back and say what all has happened over a span of time.

Feature Request 2: It also seems desirable to extend apply change into applyChanges([...]) which takes an array of changes to apply to the origin (an ordered array that is).

Do these have downsides I'm missing? Beyond the fact that I'm a random person on the internet asking for things ^_^

Thanks for he great tool by the way, if you do or do not take the request.

1) The default is an array of changes or undefined if there are none. Doesn't that already provide the total changes?

2) Code below: you're not alone on this one - I do it all the time:

function applyChanges(target, changes) {
  return changes.reduce(
    (acc, change) => {
      diff.applyChange(acc, true, change);
      return acc;
    },
    target
  );
}

Take a look at example/issue-88.js - let me know if you still really need it as part of the package.
