javascriptLodash v4 deep cloning and merge behavior for inherited properties
Property Inheritance in v4 Transitions The transition from Lodash v3 to v4 introduced significant changes in how the library handles object manipulation, specifically regarding the shift toward immutable patterns and the reduction of the API surface. A critical design consideration involves the handling of inherited properties during deep operations. While v
_.cloneDeep behavior with custom class instances and prototype preservation
The _.cloneDeep function in lodash is designed to recursively clone nested objects, arrays, and ES6 collections like Map and Set while managing circular references to prevent stack overflows. A specific design constraint exists regarding prototype chains. While the function creates new instances of built-in types, it primarily clones enumerable own propertie
