Do closures capture objects by reference and primitives by value?
Short interview answer
That wording is misleading. Closures reference lexical bindings. A binding may currently contain a primitive or an object reference, and reassignment changes what later reads observe.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
