Ternary return a value. As a result it would better to rewrite above as const check=this.props.favList.find(movie => movie.imdbID==this.props.id)? {fav_on:true}:{fav_on:false}

Better still, since we use check in cx, we can simplify above to const favOn=this.props.favList.find(movie => movie.imdbID==this.props.id); and then use it as
const classes=cx('material-icons md-24',{fav_on: favOn}); in cx

It would be cleaner to calculate to generate a favList array in if/else, then you can set it in state and localStorage after and you would not need to duplicate code. Also, since favList would be precomputed we would not need to use a callback when setting it in localStorage

it would be better to create a favList array first then set it both in state and localStorage without using the callback

It would better to use favList from state rather than getting it from localStorage. favList in state should have same items.

Nice work. A few bits could be a slightly more concise or tidied up but very nice work overall |
