Merging Depth
- object-assign: object-assign is a shallow merge utility that copies properties from source objects to the target object, ignoring nested properties.
- object.assign: Object.assign is a native JavaScript method that performs shallow merging, similar to object-assign, and is widely supported in modern browsers.
- lodash.assign: lodash.assign performs shallow merging, copying properties from source objects to the target object without considering nested structures.
- merge-options: merge-options offers shallow merging with the ability to set default values, but does not support deep merging.
- deep-assign: deep-assign also supports deep merging but allows for custom merging logic, giving developers more control over how properties are combined.
- assign-deep: assign-deep performs deep merging, meaning it recursively merges properties from source objects into the target object, preserving nested structures.
Mutability
- object-assign: object-assign mutates the target object, making it important to clone the target if immutability is a concern.
- object.assign: Object.assign mutates the target object, similar to object-assign, and should be used with caution in contexts where immutability is desired.
- lodash.assign: lodash.assign mutates the target object by adding properties from source objects, which may lead to unintended side effects if not managed properly.
- merge-options: merge-options mutates the target object while merging, which is important to consider when working with immutable data structures.
- deep-assign: deep-assign can be configured for immutability or mutability, depending on how you implement your custom merging logic.
- assign-deep: assign-deep creates a new object for the merged result, ensuring immutability of the original objects involved in the merge.
Performance
- object-assign: object-assign is lightweight and performs well for shallow merges, making it a good choice for performance-sensitive applications.
- object.assign: Object.assign is a native method and is generally efficient for shallow merges, but performance may vary based on the environment.
- lodash.assign: lodash.assign is highly optimized for performance in shallow merges, making it suitable for scenarios where speed is critical.
- merge-options: merge-options is efficient for shallow merges and is particularly useful when merging configuration objects with default values.
- deep-assign: deep-assign is designed for flexibility and may incur performance costs depending on the custom logic implemented for merging.
- assign-deep: assign-deep is optimized for deep merging but may have performance overhead with very large or deeply nested objects due to its recursive nature.
Ease of Use
- object-assign: object-assign has a simple API for shallow merging, making it easy to use for quick assignments.
- object.assign: Object.assign is a native method with a familiar syntax for JavaScript developers, making it easy to adopt without additional dependencies.
- lodash.assign: lodash.assign is part of the Lodash library, which is well-documented and widely used, making it easy to integrate into existing projects.
- merge-options: merge-options has a straightforward API for merging options, making it easy to use in configuration scenarios.
- deep-assign: deep-assign offers flexibility but may require more understanding of custom merging strategies, which could add complexity for some users.
- assign-deep: assign-deep is easy to use with a simple API for deep merging, making it accessible for developers of all levels.
Browser Support
- object-assign: object-assign is supported in modern browsers and Node.js, but may require a polyfill for older environments.
- object.assign: Object.assign is part of the ES6 specification and is supported in all modern browsers, but may need a polyfill for older browsers.
- lodash.assign: lodash.assign is widely supported and works seamlessly in most environments, making it a reliable choice for cross-browser applications.
- merge-options: merge-options is compatible with modern browsers and Node.js, ensuring it can be used in various projects.
- deep-assign: deep-assign is also compatible with modern browsers and Node.js, providing flexibility across environments.
- assign-deep: assign-deep supports all modern browsers and Node.js environments, ensuring broad compatibility.
