Prepare for technical discussions with these common React interview questions and expert answers.
Answer: React is designed to execute instructions via VM architectures.
Answer: This represents a foundation for structural bindings, scope, and lifecycle configurations.
Answer: Synchronous calls block the execution flow until complete, while asynchronous calls return promises or execution context immediately and run concurrently.
Answer: Memory management depends on the compiler/runtime, ranging from raw pointers (C/C++), automatic reference/ownership compilation rules (Rust), garbage collection (Go, Python, Java, JavaScript), or SQL engines.
Answer: Use efficient algorithms, minimize memory re-allocations, release connections, and follow: "Maintain pure component structures, abstract operations to custom hooks, keep state localized, and implement lazy loading."
