How does Object.assign affect performance in JavaScript?

How does Object.assign affect performance in JavaScript?

Object.assign can impact performance, especially with large objects or deep cloning. It creates a shallow copy, which can be faster than deep cloning methods.

Are there any alternatives to Object.assign that perform better?

Yes, alternatives like the spread operator ({...obj}) can be more performant in some cases, especially for shallow copies.

What about using libraries like Lodash for object merging?

Lodash's _.merge is powerful for deep merging but can be slower than Object.assign for shallow merges due to its complexity.

How can I measure the performance of these methods?

You can use the console.time() and console.timeEnd() methods to measure execution time for each method in your code.

Is there a specific scenario where Object.assign is preferred?

Object.assign is preferred for simple shallow copies and when you need to merge properties from multiple sources efficiently.
