Changelog

3.0

Possible breaking change merge not does not accept options anymore
Removed dependency on deepmerge

2.0

Possible breaking change The library now has dependencies and is building with Rollup, therefore the UMD entry point is now dist/object-path-immutable. If you are using this object-path-immutable with Node or another module bundler, this change should not affect you.
Added merge function

1.0

Breaking change: The way the library handles empty paths has changed. Before this change,all the methods were returning the original object. The new behavior is as follows.
- set(src, path, value): value is returned
- update(src, path, updater): value will be passed to updater() and the result returned
- set(src, path, ...values): values will be concatenated to src if src is an array, otherwise values will be returned
- insert(src, path, value, at): if src is an array then it will be cloned and value will be inserted at at, otherwise [value] will be returned
- del(src, path): returns undefined
- assign(src, path, target): Target is assigned to a clone of src and returned
