Can a microtask interrupt synchronous JavaScript?
Short interview answer
No. The current job or task runs to completion first. Microtasks drain at defined checkpoints after the stack unwinds, not in the middle of an ordinary statement sequence.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
