How to verify that part of the draft is array.

[Jakub Hromek]

🙋‍♂ Question

I have tree data structure where i can have any value. When browsing draft I need to check if the value is array, but draft is object.

I try Array.isArray(current(draftValue)) but i can have array witch millions of object. I feel potential performance issue.

I also thought to check presence of map, concat, forEach ... etc.

Is there any easy way to verify this?

Thank you

I think Array.isArray(draftValue) should also work? Or are you using Immer in ES5 mode?

You are right, i must try it again in my project. In sandbox all works correctly.
