how to use the flattendeep function from the lodash library in typescript

To use the flattenDeep function from the Lodash library in TypeScript, first, make sure you've installed Lodash as a dependency using your package manager of choice. Then, import the flattenDeep function from Lodash:

index.ts
import { flattenDeep } from 'lodash';

2 lines

Now, you can use the flattenDeep function in your TypeScript code. For example:

index.ts
const nestedArray = [1, [2, [3, [4]], 5]];

const flattenedArray = flattenDeep(nestedArray);

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

In this example, we're using the flattenDeep function to flatten a nested array containing arrays with varying levels of depth. The function takes an array (in this case, nestedArray) as its argument and returns a new flattened array (in this case, flattenedArray). Finally, we're logging the flattened array to the console.

Make sure you're importing the flattenDeep function from the correct package path and that typescript has imported types for lodash.
