Unable to access React instance (this) inside event handler [duplicate]

Answer 1

In case you want to keep the bind in constructor syntax, you can use the proposal-bind-operator and transform your code like follow :

constructor() {
  this.changeContent = ::this.changeContent;
}

Instead of :

constructor() {
  this.changeContent = this.changeContent.bind(this);
}

much simpler, no need of bind(this) or fatArrow.
