Changelog

4.0

• Breaking change: the previous default export is now called wrap()
• Possible breaking change: object-path-immutable now uses ES modules which means if you are in an ESM environment you will have to use named exports.

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
