I’m completely incapable of mimicing Mosh in the Passing data to Components episode (E.3 of Composing Components.
Everything exept
state = {
value: this.props.value
}
I get an error that says: Cannot read property ‘value’ of undefined
I’ve checked the value attribute of but there’s nothing wrong.
Did something change in react or something?

It suddenly worked and I have no idea why
Ensure that you have passed the value prop properly
Make the following change in the constructor and it will work
state = {
value: this.props.value
};
constructor(props){
super(props)
this.handleIncrement = this.handleIncrement.bind(this);
}
