I am getting confusion of observable and subscribe and promise in angular 8.How can I easily understand about observable,subscribe,promise. Anyone Can you explain about subscribe with observable? observable work as a data storage? If we use subscribe can we get bunch of value or single value one by one?

                    1It would be better if you specified *what specifically* you are not understanding. – Igor May 05 '20 at 13:47

                    `If we use subscribe can we get bunch of value or single value one by one` ← Yes and Yes. – Igor May 05 '20 at 14:37

                    `observable work as a data storage` ← You can cache the result so that way it is only ever fired once using shareReplay. Then all subscribers get the same value every time. – Igor May 05 '20 at 14:38
