🔄 Deep Clone Objects

Deep cloning with Marshal lets you duplicate complex Ruby objects (including nested arrays and hashes) without retaining references to the originals. This approach is significantly faster than manual deep-copy implementations for large data structures. Use Marshal.dump and Marshal.load back-to-back to produce an independent copy.

original = { users: [{ name: "Alice" }, { name: "Bob" }], settings: { theme: "dark" } }
clone = Marshal.load(Marshal.dump(original))

# Modifying the clone doesn't affect the original
clone[:users][0][:name] = "Carol"
puts original[:users][0][:name]  # => "Alice"
