Can a single form mix controlled and uncontrolled inputs?
Short interview answer
Yes — it's common for most fields to be uncontrolled while one or two fields that need live reactivity, like an inline-validated email field, are controlled; the two models coexist fine as long as no single input mixes them.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
