Spread Operator vs Lodash: Which to Use?

What are the main differences between the spread operator and Lodash?

The spread operator is a native JavaScript feature for expanding iterable elements, while Lodash is a utility library that provides many functions, including similar functionalities to the spread operator.

Can you give me an example of how to use both?

Sure! Using the spread operator: const arr1 = [1, 2]; const arr2 = [3, 4]; const combined = [...arr1, ...arr2]; With Lodash: const _ = require('lodash'); const combined = _.concat(arr1, arr2); Both will result in [1, 2, 3, 4].

When should I prefer using Lodash over the spread operator?

You might prefer Lodash when you need more complex operations, like deep merging or manipulating objects, as it offers a wide range of utility functions.

Are there any performance differences between the two?

Generally, the spread operator is faster since it's a native feature, but Lodash can be more optimized for specific tasks. It depends on the use case.
