What is the "Dirty" in React.js?

Question

I try to understand React.js and often come across the term "Dirty" like dirty validation / validation, dirty data, dirty model

I followed this question , but could not understand what the term Dirty actually means , and why we call it dirty.

Answer 1

Dirty data is data that has recently been changed and the DOM has not yet been re-mapped in accordance with these changes. So a dirty check is the difference between the next state and the current state.

Answer 2

Dirty - , , . , .
