`object.assign()`
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
`Object.assign()` is a method in JavaScript that copies the values of all enumerable own properties from one or more source objects to a target object, effectively merging objects or cloning their properties. It is often used for shallow copying and object composition.
Key Features
- Performs shallow copy of source objects to a target object
- Merges multiple objects into one
- Modifies the target object in-place
- Returns the target object after assignment
- Useful for object cloning and property extension
Pros
- Provides an easy way to merge objects or clone properties
- Supports multiple source objects for combined updates
- Built-in method with widespread support in JavaScript environments
- Useful for immutable-like updates when working with object copies
Cons
- Performs a shallow copy, not a deep clone, which can lead to unexpected shared references in nested objects
- Overwrites properties without warning if there are conflicts
- Cannot be used to copy getter/setter functions properly
- Limited to enumerable own properties, ignoring inherited properties
