Do i need to learn react?

I'm Full-stack developer with expertise in creating webapps and admin panels.

I have experience working in PHP-laravel framework for backend and Javascript-Vue framework in frontend. I have also worked on Ionic-Vue for creating mobile applications.

I'm curious on learning blockchain development. I have read many articles stating you need to have knowledge of react.js.

what will be the learning curve for blockchain development?

Any suggestions/blogs would be helpful.
