setImmediate vs. nextTick

Question

Node.js version 0.10 was released today and introduced setImmediate. The API changes documentation suggests using it when doing recursive nextTick

Answer 1

In the comments in the answer, it does not explicitly state that nextTick shifted from Macrosemantics to Microsemantics.

before node 0.9 (when setImmediate was introduced), nextTick operated at the start of the next callstack.

since node 0.9, nextTick operates at the end of the existing callstack, whereas setImmediate is at the start of the next callstack
