TypeError: onVideoSelect is not a function

[Vinay Sagar Sharma]

this is my index.js file
render() { return ( <div> <SearchBar /> <VideoDetail video={this.state.selectedVideo} /> <VideoList onVideoSelect={selectedVideo => this.setState({selectedVideo}) } this.setState({selectedVideo}) } videos ={this.state.videos} /> </div> ); } }
When I used to run my code on localhost server console gives this error. Anyone can have any idea what went wrong?
