Great writeup [Suprabha Supi](https://hashnode.com/@suprabhasupi). 👍 I would also like to add that:

-   Pure functions allow us to write parallel code.
-   Pure functions output can also be cachable because they always return the same output, increasing code performance.
-   Pure function should be composable or obey the function composition concept.
