Load into the specified `extension` the extension of `path`. If the optionally specified `rootEnd` offset is non‐negative, it is taken as the position in `path` of the character following the root. Return 0 if the path has an extension, and a non‐zero value otherwise. See []and Performance). See also  for the definition of leaf and root.
