Advanced usage

Options

{
    // Decremented with each recursion for each nested object, halting the clone at 0
    // A halted clone will preserve references to any remaining values
    depth: 8,

    // Determines whether recursing will occur. When this type matches, it will be iterated over.
    types: { object: true, array: true }
    types: [ "object", "array" ] // Can also be an array of type strings
