What is the difference between native and library object merging in JavaScript?

What is the difference between native and library object merging in JavaScript?

Native object merging typically refers to using built-in methods like Object.assign() or the spread operator. Library object merging often involves using utility functions from libraries like Lodash.

Can you give me an example of using Object.assign()?

Sure! Here's a simple example: const obj1 = { a: 1 }; const obj2 = { b: 2 }; const merged = Object.assign({}, obj1, obj2); // merged is { a: 1, b: 2 }.

What about using Lodash for merging?

With Lodash, you can use _.merge() like this: const obj1 = { a: 1 }; const obj2 = { b: 2 }; const merged = _.merge({}, obj1, obj2); // merged is { a: 1, b: 2 }.

Are there any performance differences between the two methods?

Yes, native methods are generally faster since they are optimized in the JavaScript engine, while library methods may add overhead.
