I can’t find the text you quoted. The article starts off: > A hash function is any function that can be used to map data of arbitrary size to fixed-size values

I can’t find the text you quoted. The article starts off:
> A hash function is any function that can be used to map data of arbitrary size to fixed-size values
And the first sentence in the section you link says
> A good hash function should map the expected inputs as evenly as possible over its output range.
