React - uncaught TypeError: Cannot read property 'setState' of undefined

Question

I am getting the following error

Uncaught TypeError: Cannot read property \'setState\' of undefined

even after binding delta in

Answer 1

When using ES6 code in React always use arrow functions, because the this context is automatically binded with it

Use this:

(videos) => {
    this.setState({ videos: videos });
    console.log(this.state.videos);
};

instead of:

function(videos) {
    this.setState({ videos: videos });
    console.log(this.state.videos);
};
