Swift, ARC and memory footprint vs JVM and GC

Think misconception is to equal GC to JVM GC, which is not always true. What'd you say about Haskell or Erlang GC?

Java garbage collectors are more performant than those in either Haskell or Erlang.

Additionally, since the sweep pass touches almost all RAM in the process, they tend to be very power inefficient (leading to reduced battery life).

This is clearly false with a generational garbage collector.

Reference counting vs GC involves a complex set of tradeoffs but it’s not true that one is simply better than the other, and we shouldn’t make false claims when advocating either approach.
