Delta diff() method returning wrong value..

[naveenrsaradhya]

Old Text : I am Naveen
New Text : I am visakh
I am soumya

I tried find difference between above two versions ...

Old Delta : "{"ops":[{"insert":"I am Naveen\n"}]}"
New Delta : "{"ops":[{"insert":"I am visakh\nI am soumya\n"}]}"

Diff it is giving as : "{"ops":[{"retain":5},{"insert":"vis"},{"delete":1},{"retain":1},{"insert":"kh\nI am soumya"},{"delete":4}]}"

Here after "vis" insertion it is giving as deleted 1 which is wrong.
It should give as visakh inserted then delete right ??
Do am wrong??

It's doing a character level diff not word level and the output is correct.

Ok even character also there character no match..
up to I am is correct after Naveen and visakh if compare character level still wrong answer right?

I've checked again and the output is correct. I don't know where the misunderstanding is but suggest you re-review the documentation and play around with different simpler inputs.
