Deep merging in JavaScript refers to the process of merging two or more objects deeply, ensuring that nested structures, including arrays, are merged recursively. While JavaScript provides the spread operator (...) for shallow merging, it lacks native support for deep merging. This limitation becomes apparent when dealing with complex objects or arrays nested within objects.

To address this gap, developers commonly turn to libraries like deepmerge. This lightweight and widely-used library enables seamless deep merging of JavaScript objects, handling nested structures with ease. By leveraging deepmerge, developers can efficiently combine objects, preserving the integrity of nested arrays and objects throughout the merge process.

The library's versatility and simplicity make it a popular choice for projects requiring robust object manipulation. Whether merging configurations, state objects in React applications, or any other complex data structures, deepmerge provides a reliable solution, enhancing the flexibility and maintainability of JavaScript codebases.
