Came across a short article, it appears the phrase "Require should be cached".
What does it mean?

The fact that either it is very crooked translation or the author's problems with the presentation of ideas or both.
Read the spec for require all. There is about "caching" and about "the code will execute one time."

Something like: if you requires the same module in multiple places, it needs to be loaded once and reused in the right places
