Zero filled array creation (v19)

Revision 19 of this benchmark created by Victor on

Description

Creating an array filled with zeros. Which is the fastest method? These methods are useful for arrays filled with a single element, except for the typed array conversion which works only with zeros. Only the first two methods are useful with incremental values or callbacks.
