[Jamming project]

Hi there,
I’ve got stuck on Jammming project,

I checked React Dev Tool and my props actually an array,. but why it cannot use map method.

Hi TagRunner, TypeError should suggest what the problem is. this.props.tracks should be an array data type, because the map() is an array method. I would first look through and see if the this.props.tracks is a actually an array.

Also, this thread is already discussing the same problem: Jammming project - TrackList props are showing in dev tools but trying to use map() on them gives a TypeError showing as undefined
