31. RXJS - The mergeMap operator - Map values to Inner Obs & Subscribe Concurrently | (Hindi)
In this video, we will learn the RxJS mergeMap operator. The mergeMap operator is a Higher-order mapping operator to work with Higher order Observables. The mergeMap operator is a combination of two operators merge and map. This operator maps the values to Inner Observables and concurrently subscribes to them.
