After that, you can import the unzipWith function from the lodash package in your TypeScript file as follows:

index.ts
import * as _ from "lodash";

const zipped: [string[], number[]] = [['a', 1], ['b', 2], ['c', 3]];
const result = _.unzipWith(zipped, (arr) => {
    return arr.reduce((acc, curr) => acc + curr, 0);
});

console.log(result);

In the above example, we have created a zipped array with two sub-arrays containing string and number values. We passed this array as the first argument to the unzipWith function along with a custom function as the second argument. The custom function takes each sub-array as an argument, and we have used the reduce function to sum up the values in each sub-array. Finally, we log the result to the console.

The unzipWith function returns a new array with unziped values after applying the custom function to each array.
