Thanks 🙏

For some context why this change is made: https://2ality.com/2016/10/rest-spread-properties.html#spreading-objects-versus-object.assign()

TLDR: Object.assign in the way used here calls setters on the item and allows setters to be called.

I still need to think about any issues with this change such that users may perceive this as a breaking change - do you have any thoughts on that?

[xswei]

Maybe you can let the user decide which way to choose, such as configuration: clone: 'spread' | 'assign'

Sorry for the delay on this.

I like the idea of giving an option to the user – implemented that change in #44 .

Released in https://www.npmjs.com/package/performant-array-to-tree/v/1.11.0

Thanks for your contribution!

Closes #34
