When value is assigned to components state, why console.log prints the previous state?

Question

I\'m sending values of numbers from Numbers component to Main component. Everything is working fine until I set that value in my Main component to that component\'s state.<

Answer 1

Probably because the console.log is triggered before the new state has been really set.

You should use the function:

componentDidUpdate: function() {
    console.log(this.state.number);
}

This function is triggered each time the state is updated.

Hope it helps
