🛠️ How to Use

To install the package, run:

npm install smart-flatten

Basic Flattening

Flatten an array up to a given depth.

const smartFlatten = require('smart-flatten');
const flatArray = smartFlatten([1, [2, [3, [4]]]], 3);
// Output: [1, 2, 3, 4]

With Filtering

Use a filter function to keep only the elements you want.

const flatArray = smartFlatten([1, [2, [3, [4]]]], 3, x => x > 2);
// Output: [3, 4]

With Sorting

You can sort the flattened array using a custom sort function.

const flatArray = smartFlatten([4, [1, [3, [2]]]], 3, null, (a, b) => a - b);
// Output: [1, 2, 3, 4]

Remove Duplicates

Easily remove duplicate items from the flattened array.

const flatArray = smartFlatten([1, [2, [2, [3, 3]]], 1], 3, null, null, true);
// Output: [1, 2, 3]

With React

Smart-Flatten is also React-friendly. Here's how you can use it to render a nested array.

import React from 'react';
import smartFlatten from 'smart-flatten';

const NestedList = ({ nestedArray }) => {
  const flatArray = smartFlatten(nestedArray, 3);

  return (
    <ul>
      {flatArray.map((item, index) => (
        <li key={index}>{item}</li>
      ))}
    </ul>
  );
};

📚 Function Parameters

smartFlatten(array, depth, filterFn, sortFn, removeDuplicates)

Here's what each parameter is for:

array (required)

The array you want to flatten. It can contain nested arrays up to any level.

depth (optional, default = 1)

The maximum depth to flatten. If you want to flatten all nested arrays, regardless of how deeply nested they are, you can set this to Infinity.

filterFn (optional)

A function to filter the elements of the array. It should return true for elements you want to keep, and false for those you want to remove.

sortFn (optional)

A function to sort the elements of the array. This works the same way as JavaScript's native .sort() method.

removeDuplicates (optional, default = false)

A boolean flag to remove duplicate elements. When set to true, duplicates will be removed from the flattened array.
