extensionsWith

extensionsWith is a JavaScript library designed to simplify the process of adding extensions to objects. It provides a method that allows developers to merge properties from one or more source objects into a target object. This merging process can be configured to handle different scenarios, such as overwriting existing properties or preserving them. The library aims to offer a more flexible and controlled approach to extending objects compared to native JavaScript methods like `Object.assign`.

The primary function offered by extensionsWith typically takes a target object as the first argument, followed by any number of source objects. The properties from these source objects are then applied to the target object. Developers can specify options to control how the merging occurs. For instance, it might be possible to define a custom merging strategy for specific data types, such as arrays or nested objects, ensuring that complex structures are handled appropriately rather than simply being overwritten.

The library's advantages lie in its configurability and the potential for more nuanced object extension. This can be particularly useful in frameworks or applications where complex state management or data manipulation is required. By providing a dedicated tool for this task, extensionsWith seeks to reduce boilerplate code and improve the readability and maintainability of JavaScript projects that rely heavily on object composition.
