objectmerging
Object merging refers to the process of combining two or more objects into a single object by taking properties from source objects and applying them to a target object. The merge typically resolves conflicting keys by favoring properties from later sources. There are two common flavors: shallow merge, which copies enumerable own properties at one level; and deep (recursive) merge, which traverses nested objects to merge their properties.
In many programming environments, merges can be performed mutating the target or by returning a new object.
Typical use cases include combining default options with user-provided options, assembling configuration from multiple sources, or
Potential pitfalls include unintended mutation of inputs, loss of nested defaults, and prototype pollution risks if
