Where is data stored in React.js? [closed]

Question

For an interview, I was asked ,"where is data stored in React.js?" I tried saying state, props, and React doesn't store data. I'm not sure what answer he was looking for. What's the best way to answer this question? Note, he's primarily a Java programmer.

Answer 1

Without his mindset it is kinda of hard to say...

• Hardware - It's stored in memory
• Classic React - Props and State are completely legitimate answers
• React-Redux - It's stored in the 'store'

I think this is a poor question to ask an interviewee without any real context. Java programmer or not, it sounds like he doesn't entirely understand what he is talking about. You might have dodged a bullet not working for that company.

Answer 2

I would have said React can use a combination of sessionStorage, localStorage, state, store, and this, to hold data, however storing data would be whatever database you setup to use it with.
