Clearing state es6 React

Question

I am trying to clear a components state but can\'t find a reference for the es6 syntax. I was using:

this.replaceState(this.getInitialState());

Answer 1

This is how I handle it:

class MyComponent extends React.Component{
  constructor(props){
    super(props);
    this._initState = {
        a: 1,
        b: 2
      }
    this.state = this._initState;
  }

  _resetState(){
     this.setState(this._initState);
   }
}

Update: Actually this is wrong. For future readers please refer to @RaptoX answer. Also, you can use an Immutable library in order to prevent weird state modification caused by reference assignation.
