How can I use Lodash to flatten an array?

How can I use Lodash to flatten an array?

You can use the _.flatten method from Lodash to flatten a nested array. For example, _.flatten([[1, 2], [3, 4]]) will return [1, 2, 3, 4].

What if I have a deeply nested array?

In that case, you can use _.flattenDeep. For example, _.flattenDeep([1, [2, [3, [4]]]]) will return [1, 2, 3, 4].

Are there any performance considerations when using these methods?

Yes, _.flatten is generally faster for shallow arrays, while _.flattenDeep can be slower for very deep nesting due to recursion.

Can I use Lodash with modern JavaScript features?

Absolutely! Lodash works well with modern JavaScript, and you can use it alongside ES6 features like arrow functions and destructuring.
