scan, reduce, max |
This is how a ❚ max operator would operate with an input stream:
- When the input stream completes, the output stream:
- emits the largest value emitted on the input stream
- and immediately completes
Some reactive stream libraries (eg. RxJS) provide this ❚ max operator, while others don't. How would you code max yourself?
In RxJS, ❚ min and ❚ max accept on optional comparer function as an argument.
For example:
{:.w400}
{:.w300}
