 Reference type  : slice channel map

 differences between new     and  make to create reference types

  New allocates a 0 value space of that size based on the size of the type, and then returns the first address of the space.   

Make is translated by the compiler into a concrete creation function, which allocates memory and initializes member variables, returning objects, not pointers,
