To use the flatten function from lodash in Javascript, you first need to install the lodash library via npm or yarn by running the following command in your project directory:

Next, you can import the flatten function from lodash in your Javascript code by adding the following line:

index.tsx
const flatten = require('lodash/flatten');

2 lines

Alternatively, you can also import the entire lodash library by adding the following line:

index.tsx
const _ = require('lodash');

2 lines

After importing the flatten function, you can use it to flatten an array of arrays by passing the array as an argument:

index.tsx
const originalArray = [[1, 2], [3, 4], [5, 6]];
const flattenedArray = flatten(originalArray);

console.log(flattenedArray); // Output: [1, 2, 3, 4, 5, 6]

5 lines

In the above code, the flatten function takes the original array and flattens it into a single array with all the elements in it.
