# RxJS vs Promises |
|
|
|
In a nutshell, the main differences between the Promise and the Observable are as follows: |
|
|
|
- The Promise is eager, whereas the Observable is lazy, |
|
- The Promise is always asynchronous, while the Observable can be either asynchronous or synchronous, |
|
- The Promise can provide a single value, whereas the Observable is a stream of values (from 0 to multiple values), |
|
you can apply RxJS operators to the Observable to get a new tailored stream. |
