What are some alternatives to Object.assign?

What are some alternatives to Object.assign in JavaScript?

There are several alternatives to Object.assign, such as the spread operator, lodash's merge function, and using Object.entries with reduce.

Can you explain how the spread operator works as an alternative?

Sure! The spread operator allows you to create a new object by spreading the properties of existing objects. For example: const newObj = {...obj1, ...obj2}; merges obj1 and obj2.

What about using lodash? How does that compare?

Lodash's _.merge function is more powerful as it deeply merges objects, unlike Object.assign which only performs a shallow merge.

Are there any performance considerations I should be aware of?

Yes, the spread operator and Object.assign are generally faster for shallow merges, while lodash's merge can be slower due to its deep merging capabilities.
