Package description
The arr-flatten npm package is a utility for flattening nested arrays into a single-level array. It is a simple and focused package that does not handle arguments other than arrays (e.g., it does not flatten array-like objects).
Flatten nested arrays
This feature allows you to flatten a deeply nested array into a single-level array. The code sample demonstrates how to use the `.flat()` method to flatten an array with multiple levels of nesting.
[1, [2, [3, [4]], 5]].flat()Lodash provides a method called `flatten` that can flatten arrays up to one level deep. It is part of the larger Lodash library, which offers a wide range of utilities for working with arrays, objects, and other types. Compared to arr-flatten, lodash.flatten is part of a larger utility library and may not be as lightweight if you only need to flatten arrays.
The `flat` package offers functionality to flatten arrays with additional options, such as specifying the depth to which the array should be flattened. It can also flatten array-like objects, unlike arr-flatten. This package provides more flexibility and features compared to arr-flatten, which is more minimalistic.
Readme
Recursively flatten an array or arrays. This is the fastest implementation of array flatten.
Why another flatten utility? I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.
