Julia: UndefVarError: randperm not defined

Question

I am currently staring with Julia 1.0.0 under Windows 10. When using a function randperm(n) where n is an integer number, I got an error message:

ERROR: UndefVarError: randperm not defined.

Presumably, I have not loaded a library that contains this function. So, could anyone please tell me which library should I load so that I can use that function? Thank you in advance!

If you're used to the syntax and idioms of v0.6, be aware the core devs are recommending that users work on v0.7 for a month or so, until they get used to all the breaking changes (which all generate descriptive warnings on v0.7, as others have mentioned below). — Colin T Bowers

You need to load standard library Random, e.g.:

julia> using Random

julia> randperm(10)
10-element Array{Int64,1}:
  6
  3
  7
 10
  2
  8
