What it does

Warns the usage of UNSAFE_componentWillMount in class components.

Using unsafe lifecycle methods like UNSAFE_componentWillMount makes your component's behavior less predictable and are more likely to cause bugs.

import React from "react";
 
class MyComponent extends React.Component {
  UNSAFE_componentWillMount() {
    // ...
  }
}
