What is the difference between Object.create and new in JavaScript?
Object.create(proto) creates an object with the specified prototype (no constructor call). new Constructor() calls the constructor function and sets the prototype to Constructor.prototype. Object.create is for direct prototype setting; new is for instantiation.

Copies properties from source objects to a target object (shallow copy). Object.assign({}, defaults, overrides) creates a new object with merged properties. It does not copy inherited properties, only own enumerable properties.
When you want to create an object with a specific prototype without calling a constructor. For example: const dog = Object.create(animal) creates an object that inherits from animal without running any constructor code.
No. Object.assign does a shallow copy. Nested objects are referenced, not copied. For deep copy, use structuredClone(), JSON.parse(JSON.stringify(obj)), or a library like lodash's _.cloneDeep.
