If I read that right, the sanitize function is removing all HTML tags and then slicing the string if it has more than 55 words. But won't doing such a thing remove the purpose of using dangerouslySetInnerHTML in the first place??

[pantharshit00]

I am not setting it as dangerouslySetInnerHTML. I am reading it from state. It is as because I only want the text on the post preview component not the complete html. It did the words instead of characters because last word might trim if we do substring.
