How to change any data on click?

Question

JavaScript

I want to implement an image carousel, do I understand correctly that in order for something to change (re-render) on the page, I have to change the value in the state?

Answer 1

Render is called automatically in case of:
- state changes - props
changes
- forceUpdate (I have never had to use it yet)
So, yes, you understand correctly (if we are talking about "re-rendered"). And then, you can get to the bottom that if you have a desire, you can bypass React simply by accessing the DOM to change the src of the picture, etc. (this is hardly needed in this answer, but there is such a possibility).
