What is "Dirty" in React.js?

Question

I am trying to understand React.js and often come across a term "Dirty" like dirty checker/checking, dirty data ,dirty model

I followed this question but could not make out what actually the term Dirty convey & why we call it dirty.

For people who don't like React, the whole thing is dirty... ;) — nnnnnn, Feb 08 '16 at 06:08

Dirty data - the data, that have been changed recently and DOM haven't been re-rendered according to this changes yet. So dirty checking is diff between next state and current state.

To be clear, "dirty-checking" isn't specific to React. It's just a term for one way of synchronizing application state to the DOM/UI. React uses something different: [reconciliation](https://facebook.github.io/react/docs/reconciliation.html). – rossipedia Feb 08 '16 at 08:02

Dirty is just the state of the form which tells that this form has been touched by user. This does not means that form is invalid.
